In the Old Latin Bible, which was first translated in the 100s AD & was copied by the Vaudois up to the 1700s, a 1522 copy of the Old Latin Bible has 1 John 5:7-8, which says:

[7] C. trei son liqual donan testimoni al cel, lo paire elo filh, elo sanct sperit, e aquisti trei son vn.
[8] E tres son liqual donan testimoni en terra, sperit aigua e sang, e aquisti trei son vn.

The Vaudois Old Latin Bibles were directly translated early on from Greek manuscripts; both Greek & Latin were the main commonly spoken languages of the Roman Empire during the 1st century (when the New Testament/NT was written) &  the 2nd century (when NT was translated)

The next posts will prove the Vaudois/Waldesians go back to the Apostles & their Old Latin Bibles go back to the 100sAD
