The Brethren in Christ affirm biblical infallibility: the Bible is trustworthy and authoritative for faith and practice. Scripture does not fail to accomplish its purpose of revealing God's saving purposes and guiding believers in discipleship.

However, the denomination does not require strict affirmation of absolute verbal inerrancy (that every word is inerrant in the original manuscripts). This reflects a more moderate evangelical position. Believers are encouraged to trust Scripture while acknowledging honest difficulties in interpretation and the reality of ancient literary forms, cultural contexts, and human language limitations.

The Brethren in Christ emphasize that Scripture is interpreted within the community of faith, not individualistically. Church tradition (the Anabaptist confession), reason, and experience (guided by the Spirit) assist in understanding Scripture. This communal hermeneutic protects against idiosyncratic interpretation while affirming Scripture's centrality.
