1 John 4:3
Clementine Vulgate · Berean Standard Bible
et omnis spiritus qui solvit Jesum, ex Deo non est, et hic est antichristus, de quo audistis quoniam venit, et nunc jam in mundo est.
and every spirit that does not confess Jesus (note: BYZ and TR that Jesus Christ has come in the flesh) is not from God. This is the spirit of the antichrist, which you have heard is coming and which is already in the world at this time.
