Observe here, 1. The character given of the gospel; it is the truth, the word of truth, the way of truth, confirmed by real miracles. It is divine truth, universal truth, effectual truth, and no lie; for Almighty God would never have set the seal of his omnipotency to a lie, and have confirmed it by signs and wonders, miracles and gifts of the Holy Ghost, had it been false.
Observe, 2. The character given of the heretics in St. John's days, and in our days also, they denied that Jesus is the Christ, and therein deny the Father and the Son: For whosoever denieth the Son, the same hath not the Father; that is, he denieth the Father as well as the Son; for not having the Father, and denying the Father is the same thing, He is antichrist that denieth the Father and the Son 1Jn_2:22.
This is a text in which every Socinian may see himself an atheist; he that denies the divinity of the Son, denies the Deity of the Father for such is the nature of the Godhead, that one of these cannot be alone; the Father is not without the Son, nor can be; nor can the Son be without the Father; this coherence is inseparable and inviolable; therefore he that denies the eternal Son, denies the eternal Father; and if it be Atheism to deny the Divinity of the Father, it is no less to deny the Deity of the Son; for he that denieth the Son, denieth the Father also. There is such a connection between these two, the Father and the Son, they being co-essential and co-eternal, that if you deny the divinity of the one, you deny that of the other; therefore they are atheists that deny the divinity of Christ, as well as they that deny the being of God: For he that denieth the Son, denieth the Father also.
