Reformed theology, informed by textual criticism, acknowledges that John 7:53-8:11 is absent from the oldest and most reliable manuscripts. The Westminster Confession and other Reformed standards do not deny the passage's spiritual value but recognize its questionable textual pedigree. Calvin himself noted the textual issue, and many Reformed commentaries flag it as a later addition.

However, Reformed theologians affirm that the passage's teaching—Christ's mercy and the call to repentance—does not contradict Scripture and aligns with biblical theology. The doctrine of Christ as judge and merciful savior is well-established throughout Scripture. The passage may be edifying and teach important truths, but Reformed epistemology requires acknowledging its manuscript status and not claiming it with certainty for doctrine.
