The 'Comma Johanneum' (1 John 5:7-8) is not found in the earliest Greek manuscripts but appears in Latin and later tradition. The Amish recognize this implicitly through textual exposure. However, Amish affirmation of the Trinity does not depend on this verse—it is affirmed through the Dordrecht Confession and other scriptural testimony.

The Amish pragmatic approach: if the verse appears in their Bible, its theological content is true; but its absence from earliest MSS does not disturb their faith. The doctrine of the Trinity is so foundational that textual questions do not create theological crisis.
