Integrity of Christian Oaths and Promises in Scripture
The Biblical Basis of Christian Oaths and Promises
The integrity of Christian oaths and promises is rooted in Scripture, where making and keeping vows is considered a serious matter. In Numbers 30:2, it is written, "When a man vows a vow to Yahweh, or swears an oath to bind his soul with a bond, he shall not break his word. He shall do according to all that proceeds out of his mouth" [2]. This principle underscores the importance of faithfulness to one's commitments.
The biblical teaching on oaths is further nuanced in Jesus' teaching in Matthew 5:33-37, where He summarizes the Old Testament teaching on oaths, emphasizing the need for truthfulness in all speech. Jesus critiques the Pharisees' casuistry regarding oaths, arguing that any oath implies an appeal to God's authority, and thus breaking any oath is a breach of God's command [5]. This teaching elevates the importance of integrity in everyday speech, suggesting that a Christian's "yes" and "no" should be as binding as an oath.
The New Testament also highlights God's faithfulness to His promises. In Hebrews 6:16-18, it is noted that God confirms His promises with an oath, demonstrating His immutable nature. The author of one tradition argues that God's promises are "two immutable things" - His word and His oath - which provide a strong foundation for assurance [7]. This divine faithfulness serves as a model for human integrity in making and keeping promises.
The Psalms frequently reference God's faithfulness to His promises, with Psalm 89:34 stating, "Once have I sworn by my holiness...." This oath underscores God's commitment to His covenant with David and, by extension, to His people [6]. The Psalmist's reflections on God's faithfulness encourage believers to trust in God's promises.
In the context of Christian practice, the apostle Paul's writings emphasize the importance of integrity. In 2 Corinthians 1:20, Paul notes that all God's promises find their "yes" in Christ, and through Him, the "Amen" is spoken, reinforcing the believer's assurance [7]. This Christocentric understanding of God's promises highlights the centrality of faith in Christ for understanding and living out the integrity of Christian oaths and promises.
The early Christian community took the integrity of oaths and promises seriously, as seen in the warnings against altering the content or message of Scripture, such as in Revelation 22:18-19. Here, a curse is pronounced on anyone who adds to or subtracts from the book of Revelation, underscoring the importance of preserving the integrity of God's word [8].
Throughout Christian tradition, theologians have reflected on the significance of oaths and promises. John Chrysostom, for example, discusses the apostle Paul's use of oaths, highlighting their role in affirming the truth of the gospel message [4]. Similarly, John Gill and Matthew Henry provide insights into the Psalms, emphasizing God's faithfulness to His promises and the importance of human faithfulness in response [3, 9].
The diverse Christian traditions represented in the sources - including Nonconformist/Puritan, Eastern Orthodox, Presbyterian, Baptist/Reformed, and Methodist/Wesleyan perspectives - all underscore the biblical emphasis on the integrity of oaths and promises. While specific interpretations may vary, the core biblical principles of faithfulness, truthfulness, and the seriousness of making vows are consistently upheld.
The biblical teaching on oaths and promises is not limited to personal ethics but extends to understanding God's character and covenant faithfulness. As Torrey's Topical Textbook notes, God's promises are "confirmed by an oath" and are considered "good" and "holy" [1]. This theological foundation encourages believers to mirror God's faithfulness in their own commitments.

The Pharisees had degrees of commitment for oaths—for example, ones that did not mention God were not as binding. Jesus shows that because God is related to all things (heaven, earth, Jerusalem, my head; see also Matt 23:16-22), breaking any oath breaks God’s command (see Exod 20:7). The point is that one must be altogether truthful. Jesus’ righteousness elevates the disciple’s everyday yes and no to the level of binding oath. Oaths becom”

As "yea" is His word, so "Amen" is His oath, which makes our assurance of the fulfilment doubly sure. Compare "two immutable things (namely, His word and His oat”

He declares a curse upon anyone who alters the contents of the book or its message (cp. Deut 4:2; 12:32). The curse contrasts with the statement of blessing on all who read aloud, listen to, and obey the prophecy (Rev 1:3). At the time Revelation was written, scribes would sometimes alter books to suit their own views.
