MATTHEW 5:33-37
TEACHING ABOUT OATHS
BRIEF INTERPRETATION
Text – Matthew 5:33-37
33 “Again you have heard that it was said to your ancestors, ‘Do not take a false oath, but make good to the Lord all that you vow.’
34 But I say to you, do not swear at all; not by heaven, for it is God’s throne;
35 nor by the earth, for it is his footstool; nor by Jerusalem, for it is the city of the great King.
36 Do not swear by your head, for you cannot make a single hair white or black.
37 Let your ‘Yes’ mean ‘Yes,’ and your ‘No’ mean ‘No.’ Anything more is from the evil one.”
Introduction
Jesus continues His Sermon on the Mount by addressing the human tendency to manipulate truth through oaths and exaggerated speech. While the Old Law allowed oaths as a way to affirm truthfulness, Jesus calls His followers to such integrity that their simple word should be trustworthy without any need for swearing. This teaching reveals the holiness of speech and the sacred duty of truthfulness, for God Himself is truth. The disciple’s life must therefore reflect the faithfulness and honesty of God in all words and actions.
Historical and Jewish Context
In the Old Testament, oaths were a serious matter, made in God’s name to confirm promises or testimony (Deuteronomy 23:21–23). False oaths or invoking God’s name in vain were forbidden (Exodus 20:7; Leviticus 19:12). However, by Jesus’ time, elaborate oath formulas had developed among the Pharisees to distinguish between binding and non-binding promises. People would swear “by heaven,” “by earth,” or “by Jerusalem,” using such language to appear truthful while leaving room for deceit.
Jesus denounces this misuse of oaths as hypocrisy. Since everything in creation belongs to God—heaven, earth, and even one’s own life—invoking any part of it is indirectly swearing by God Himself. By rejecting the entire practice, Jesus insists that His followers live in such transparency and integrity that their word stands on its own. Truth should flow from sincerity, not from ritual guarantees.
Catholic Theological Perspective
In Catholic theology, this teaching upholds the virtue of truthfulness, rooted in the Eighth Commandment: “You shall not bear false witness.” Jesus calls for a purity of speech that mirrors a pure heart. The believer’s “yes” or “no” must arise from honesty, humility, and consistency. Such integrity reflects God’s own fidelity, for His word is always trustworthy and true.
This passage does not prohibit all solemn oaths, such as those made in court, in marriage, or religious vows. The Church, following Christ’s intention, distinguishes between reverent oaths—made truthfully and for serious reasons—and frivolous or deceitful oaths, which dishonor God’s name (CCC 2150–2155). What Jesus condemns is the casual or manipulative use of oaths that cheapens truth and fosters dishonesty.
By commanding simplicity of speech, Jesus invites believers to a life of inner unity—where thought, word, and deed are one. Anything beyond this simplicity, He says, “is from the evil one,” because falsehood and duplicity originate from Satan, “the father of lies” (John 8:44). The Christian’s speech must thus be sacramental in nature: a visible sign of the invisible truth of God.

Catholic Liturgical Significance
This passage is read during Ordinary Time (6th Sunday, Year A) and often referenced in catechesis on the Eighth Commandment. It teaches the faithful that truth and sincerity are acts of worship, as God is honored by honest words and faithful promises. The Church’s vows—baptismal, marital, religious, or priestly—are all made with reverence and in the awareness that every truth spoken participates in God’s own faithfulness.
Conclusion
Jesus transforms the commandment concerning oaths into a call for interior honesty and divine simplicity. The Christian life must be marked by transparent truth—free from exaggeration, manipulation, or deceit. Every word we speak should bear the light of sincerity, reflecting the trustworthiness of God Himself. To speak truthfully is not merely a moral duty but a participation in the life of the God who is Truth.
Reflection
Do my words reflect the honesty of my heart? Jesus reminds me that truth is sacred and speech is powerful. Integrity means that my “yes” and “no” must always align with my actions. Each time I speak, I am called to mirror the truthfulness of Christ, whose word never fails.
Prayer
Lord Jesus, You are the Truth that sets us free. Purify my speech from exaggeration, deceit, and false promises. Let my words be few but faithful, sincere but strong. May my “yes” mean yes, and my “no” mean no, so that my life may glorify Your truth in all I say and do. Through Christ our Lord. Amen.
DETAILED INTERPRETATION
INTRODUCTION
In Matthew 5:33-37, as part of His Sermon on the Mount, Jesus addresses the integrity of one’s word and the practice of making vows. He challenges the traditional Jewish customs where oaths were considered binding only if made in God’s name, which led to loopholes allowing dishonesty in everyday speech. Jesus calls His followers to a higher standard, emphasizing that their word should be sufficient without the need for elaborate oaths. He instructs, “Let your ‘Yes’ mean ‘Yes,’ and your ‘No’ mean ‘No’,” advocating for authenticity and reliability in all communication. This teaching critiques the misuse of oaths as a means to deceive or manipulate, calling for straightforward honesty and a deeper righteousness that reflects God’s faithfulness.
By urging His disciples not to swear at all, Jesus underscores the futility of invoking things beyond one’s control, such as heaven or earth, as guarantees of truth. He teaches that truthfulness should be the foundation of all communication, where a simple “Yes” or “No” suffices to convey sincerity and commitment. This message invites Christians to reflect on the purity of their intentions and the integrity of their words, encouraging a life that mirrors the trustworthiness of God Himself. Jesus’ teaching is a powerful reminder that genuine faith is demonstrated through truthful and consistent speech, ensuring that one’s word alone is enough to be trusted without the need for external affirmations.
Matthew 5:33 “Again you have heard that it was said to those of ancient times, ‘You shall not swear falsely, but carry out the vows you have made to the Lord.’”
In Matthew 5:33-37, part of the Sermon on the Mount, Jesus addresses the issue of making oaths and vows. He references the Old Testament teachings found in Leviticus 19:12, Numbers 30:2, and Deuteronomy 23:21-23, which emphasize the importance of truthfulness in making vows and the obligation to fulfill them once made. The Old Testament law required the Israelites to fulfill their vows to God and prohibited false swearing. An oath taken in God’s name was a solemn promise, invoking God as a witness to the truth of one’s word. Falsely swearing or breaking an oath was not just a sin against one’s neighbor but also an offense against God, as it involved His holy name.
However, Jesus expands on this teaching, urging His followers to go beyond the old law by living in such a way that oaths become unnecessary. In Matthew 5:34-37, Jesus says, “But I say to you, Do not swear at all… Let your word be ‘Yes, Yes’ or ‘No, No’; anything more than this comes from the evil one.” This reflects Jesus’ call for radical honesty and integrity in the lives of His disciples. From a Catholic perspective, this teaching underscores the call to integrity and honesty. The Catechism of the Catholic Church (CCC 2150-2154, 2466-2470) explains that while the Second Commandment forbids false oaths and emphasizes the importance of respecting God’s name in truthfulness, it also highlights that a Christian’s word should be so trustworthy that there is no need for additional assurances.
Reflection:
In a world where words can be easily manipulated and promises are often broken, Jesus calls us to a higher standard of truthfulness. As Christians, we are invited to reflect God’s truth in our daily interactions. Our words should be consistent with our actions, reflecting the integrity and honesty that Jesus exemplified. This teaching challenges us to examine our own speech and commitments, ensuring they are free from deceit and manipulation. By doing so, we become credible witnesses to the Gospel, fostering trust and sincerity in our relationships.
Jesus challenges us to be people of integrity, whose words and actions consistently reflect the truth. In a world where deception and dishonesty are common, Christians are called to stand out as witnesses to the truth. We are to speak honestly, keep our promises, and let our “yes” mean yes, and our “no” mean no. This not only builds trust in our relationships with others but also honors God, who is the ultimate Truth.
Prayer:
Heavenly Father, we thank You for the gift of Your Word and the teachings of Your Son, Jesus Christ. Help us to live with integrity and honesty, allowing our words to reflect Your truth. May our “Yes” mean “Yes,” and our “No” mean “No,” as we strive to be faithful witnesses to Your love and truth in the world. Grant us the grace to speak with sincerity and act with justice, so that we may glorify You in all that we do. Teach us to live in such a way that we bring honor to Your name, and let our lives be a testament to Your goodness. We ask this through Christ our Lord. Amen.
Matthew 5:34-35 “But I say to you, do not swear at all; not by heaven, for it is God’s throne; nor by the earth, for it is his footstool; nor by Jerusalem, for it is the city of the great King.”
This passage forms part of the Sermon on the Mount, where Jesus emphasizes truthfulness and integrity in speech, going beyond the legalistic interpretations of the law prevalent among the religious leaders of His time.
Earth as God’s footstool
This metaphor is rooted in the imagery found in Isaiah 66:1, where the Lord declares, “Heaven is my throne, and the earth is my footstool.” The term “footstool” signifies humility and lowliness, emphasizing the vast difference between God’s greatness and the earth’s insignificance in comparison.
Significance of “Earth as God’s Footstool”
1. Symbol of God’s Sovereignty: By describing the earth as His footstool, God illustrates His supreme authority and dominion over creation. It serves as a reminder of His greatness and the humility of humanity in the grand scheme of the universe.
2. Call for Humility: The imagery of a footstool, a humble piece of furniture used to rest one’s feet, underscores the need for humility among believers. It reflects the idea that, despite the earth’s vastness, it is still a mere resting place for God’s feet, highlighting the need for humans to recognize their place before God.
3. Rejection of Oaths by Earth: Jesus’ instruction not to swear by the earth is a call to recognize that such oaths are ultimately meaningless because they invoke something that belongs to God. It emphasizes the importance of truthfulness and integrity without relying on external affirmations.
In the Old Testament, oaths were permitted and often used to affirm the truth of one’s words (e.g., Deut 6:13, Num 30:2). However, Jesus presents a new standard for His followers. By prohibiting swearing by heaven, earth, or Jerusalem, He reminds His followers of the sacredness of these entities. Heaven is the throne of God, the earth is His creation, and Jerusalem is the city associated with God’s covenant with His people. Thus, swearing by these is inappropriate, as it trivializes what is holy.
The Catholic interpretation of this passage focuses on the call for Christians to live with sincerity and honesty, without resorting to oaths to guarantee their truthfulness. The Catechism of the Catholic Church (CCC 2153) teaches that while oaths are permissible for serious reasons, such as in a court of law, they should not be used lightly or as a means to deceive. The emphasis is on the integrity of one’s word, reflecting the truthfulness of God Himself. Jesus’ teaching here calls for a deeper righteousness that exceeds mere external compliance with the law, urging believers to embody the spirit of truth in their daily interactions.
Reflection
As Christians, we are called to be people of integrity, whose words can be trusted without the need for additional assurances. In our daily lives, it can be tempting to make promises or oaths to convince others of our sincerity. Yet, Jesus calls us to a higher standard – one where our word is reliable and trustworthy in itself. This passage challenges us to reflect on the authenticity of our speech and actions. Are we living in such a way that others can trust our simple “yes” or “no”? In a world where truth is often compromised, Jesus’ command challenges us to let our “yes” mean “yes” and our “no” mean “no.” By doing so, we become witnesses to the truth of the Gospel, demonstrating the reliability and faithfulness of God through our actions and words.
Prayer
Heavenly Father, we thank You for the gift of Your Word, which guides us in truth and righteousness. Grant us the grace to be people of integrity, whose words are always truthful and trustworthy. Help us to recognize the sacredness of our speech and to avoid swearing by what is holy. Strengthen us to live according to Your will, so that our lives may be a testament to Your truth. May our “yes” mean yes, and our “no” mean no, reflecting the honesty and purity of heart that Jesus calls us to. In Jesus’ name, we pray. Amen.
Matthew 5:36 “Do not swear by your head, for you cannot make a single hair white or black.”
This verse is part of a broader teaching on the nature of oaths and the importance of truthfulness in speech (Mt 5:33-37). In the Catholic tradition, this teaching emphasizes the call to integrity and honesty in all communication, reflecting God’s truth in our lives.
The context of this passage is Jesus’ Sermon on the Mount, where He addresses the misuse of oaths in His time. People would swear by various things – heaven, earth, Jerusalem, or their own heads—to add weight to their promises. However, Jesus points out that such practices are unnecessary for those who live truthfully, as God is sovereign over all creation, including our very bodies (Mt 5:34-36).
The Catholic Church teaches that while formal oaths are not inherently sinful, they should be reserved for serious matters where truth is of utmost importance, such as in legal contexts or solemn vows. The Catechism of the Catholic Church underscores that everyday honesty should make oaths unnecessary: “The Lord’s disciple swears only when it is necessary, and with great discretion” (CCC 2154). This is rooted in the belief that every word we speak should be truthful, making oaths unnecessary.
In this verse, Jesus also emphasizes the limited power humans have over their lives. By stating that we cannot make a single hair white or black, He highlights our dependence on God and the futility of swearing by things over which we have no authority. The essence of this teaching is humility and trust in God. By acknowledging that we cannot control even the most minor aspects of our lives, we are invited to live in honesty and humility, trusting that God is the ultimate authority over all things.

– Sirach 23:9: “Do not accustom your mouth to oaths, nor habitually utter the Holy Name.” The Book of Sirach also cautions against the frequent use of oaths, stressing the importance of reverence for God’s name and words.
Reflection
This passage invites Christians to reflect on the sincerity and reliability of their words. Jesus calls us to a higher standard of truthfulness, where our “yes” and “no” are sufficient without the need for additional assurances. This teaching challenges us to examine whether our lives reflect the truth of the Gospel and whether our words align with our actions. In a world where deception and half-truths are common, Christians are called to be beacons of honesty. Our integrity in speech and action should testify to our faith in Christ, who is the Truth (Jn 14:6).
As Christians, we are called to live lives of integrity, where our words reflect the truth and our actions align with God’s will. In a world where exaggeration and dishonesty often prevail, Jesus’ teaching challenges us to be people of our word, relying on God’s providence rather than our own limited power. This verse invites us to embrace humility, recognizing that our lives are in God’s hands, and to speak truthfully in all our dealings, reflecting the light of Christ in our words and actions.
Prayer
Heavenly Father, grant us the grace to speak with honesty and integrity. May our words reflect Your truth and love, and may we be faithful witnesses to the Gospel in all that we say and do. Help us to live in a way that our “yes” means “yes,” and our “no” means “no,” so that our lives may glorify You. Fill our hearts with the grace to trust in Your divine providence and to reflect Your truth in everything we say and do. We ask this through Christ our Lord. Amen.
Matthew 5:37 “Let your ‘Yes’ mean ‘Yes,’ and your ‘No’ mean ‘No.’ Anything more is from the evil one.”
This verse is part of Jesus’ Sermon on the Mount, where He addresses the importance of integrity and truthfulness in communication. Jesus emphasizes that His followers should be people of their word, whose simple affirmations or denials are sufficient without the need for additional oaths or swearing. In the context of the culture at the time, oaths were often invoked to confirm the truthfulness of one’s words. However, Jesus teaches that His disciples should live with such integrity that their simple word is as trustworthy as any oath.
Catholic Teaching and Interpretation
In Catholic teaching, this passage underscores the virtue of honesty and the importance of being trustworthy in our speech. The Catechism of the Catholic Church highlights the significance of truthfulness in all forms of communication (CCC 2466), aligning with Jesus’ directive to let our ‘Yes’ mean ‘Yes’ and our ‘No’ mean ‘No’. This call to integrity reflects the truthfulness of God Himself and challenges Christians to be sincere in their speech, avoiding deceit, exaggeration, and the unnecessary invocation of oaths.
Jesus’ warning that anything beyond this simplicity of speech comes from the evil one reminds us that the devil, known as the “father of lies” (Jn 8:44), seeks to distort truth and lead people into deception. Therefore, Christians must resist the temptation to embellish, manipulate, or falsify their words, striving instead to reflect God’s truth in all their communications.
Biblical References
1. James 5:12: “But above all, my brethren, do not swear, either by heaven or by earth or with any other oath, but let your ‘Yes’ be yes and your ‘No’ be no, so that you may not fall under condemnation.” This verse echoes Jesus’ teaching and reinforces the call to straightforward and honest communication.
2. Numbers 30:2: “When a man makes a vow to the LORD or swears an oath to bind himself by a pledge, he shall not break his word; he shall do according to all that proceeds out of his mouth.” This Old Testament reference highlights the seriousness of vows and the expectation of fulfilling them.
3. Deuteronomy 23:21-23: “When you make a vow to the LORD your God, you shall not delay to fulfill it; for the LORD your God will surely require it of you, and you will be guilty of sin. But if you refrain from vowing, you will not be guilty. You shall be careful to perform what has passed your lips, for you have voluntarily vowed to the LORD your God what you have promised with your mouth.” This passage emphasizes the importance of keeping one’s word, especially in vows made to God.
Reflection
Jesus’ teaching in Matthew 5:37 challenges us to examine the sincerity and reliability of our words. In a world where exaggeration, half-truths, and broken promises are common, Christians are called to stand out by their commitment to truth. Our words should reflect our inner integrity and the truth of the Gospel we profess. By living according to Jesus’ teaching, we can foster trust and authenticity in our relationships, both with God and others. This teaching invites us to be mindful of our speech, ensuring that we do not make promises lightly, and striving to be trustworthy in all our interactions.
Prayer
Heavenly Father, You are the source of all truth and integrity. Help us to be people of our word, whose ‘Yes’ means ‘Yes’ and ‘No’ means ‘No’. Grant us the grace to speak with honesty and to act with sincerity in all our dealings. May our words reflect Your truth and bring glory to Your name. Strengthen us to live out this call to integrity in every aspect of our lives. We ask this through Jesus Christ, Your Son, who lives and reigns with You and the Holy Spirit, one God, forever and ever. Amen.
