Assemblies of God recognizes that 1 John 5:7-8 (the 'Comma Johanneum' or 'heavenly witnesses') is a late textual addition, not found in early Greek manuscripts but appearing in some Latin sources and later printed texts. The text claims that 'three bear witness in heaven: the Father, the Word, and the Holy Ghost: and these three are one.'

While acknowledging the textual-critical judgment, the AG does not dismiss the Comma's theological content as false. The Comma states what the AG affirms on other scriptural grounds: the Trinity, the unity of the three persons, and their witness to Christ. The AG's defense of Trinitarianism rests on the cumulative witness of Scripture (John 1:1, Matthew 28:19, 2 Corinthians 13:14, Hebrews 1:8, etc.), not primarily on this single passage.

The AG's nuanced stance allows for scholarly awareness of the textual issue while maintaining theological allegiance to the truth the passage expresses. Some AG pulpits may cite the Comma when teaching the Trinity, while acknowledging its uncertain manuscript status to informed audiences. The core Trinitarian doctrine is not dependent on this verse alone.
