135. John, likewise, saith that heretics are Antichrists, 1 John ii. 18 ff. plainly marking out the Arians. For this [Arian] heresy began to be after all other heresies, and hath gathered the poisons of all. As it is written of the Antichrist, that “he opened his mouth to blasphemy against God, to blaspheme His Name, and to make war with His saints,” Rev. xiii. 6. so do they also dishonour the Son of God, and His martyrs have they not spared.

And thus he who saith that Jesus is not the Christ, the same is Antichrist; he who denies the Saviour of the world, denies Jesus; he who denies the Son, denies the Father also, for it is written; “Every one which denieth the Son, denieth the Father likewise.” 1 John ii. 23.
