ISB ~ 1 John 5 v7 - 8

A handful of late Greek manuscripts, along with a few medieval Vulgate manuscripts and the Clementine Vulgate of 1592, expand these verses with the line:“There are three who give witness in heaven: the Father, the Word, and Holy Spirit, and these three are one” (inserted either in 5:7 or in 5:8 with minimal variation). This is known as the “Johannine Comma” or the “heavenly witnesses” text. Despite the fact that this line is a clear expression of trinitarian doctrine, the Holy Office decreed in 1927 that Catholic scholarship, after careful examination of the manuscript evidence, is not bound to accept the text as part of the original wording of 1 John. The reading does not appear in the Nova Vulgata, the updated edition of the Latin Vulgate Bible approved by Pope John Paul II (1979).
