The Church of the Brethren acknowledges that 1 John 5:7-8, in the Trinitarian form, is likely a later addition to the text not found in the earliest manuscripts. The Brethren approach combines textual honesty with doctrinal affirmation: the Church affirms the Trinity based on clearer and more original scriptural passages while recognizing that 1 John 5:7-8 in its longer form is textually disputed.

The Brethren commitment to both scholarly awareness and faithful doctrine allows them to hold that the Trinitarian faith is well-supported by Scripture even if this particular passage is textually questionable.
