Who is the liar but he who denies that Jesus is the Christ? This is the Antichrist, he who denies the Father and the Son.
That denieth the Father and the Son - That denies the special truths pertaining to God the Father, and to the Son of God. The charge here is not that they entertained incorrect views of God “as such” - as almighty, eternal, most wise, and good; but that they denied the doctrines which religion taught respecting God as Father and Son. Their opinions tended to a denial of what was revealed respecting God as a Father - not in the general sense of being the “Father” of the universe, but in the particular sense of his relation to the Son. It cannot be supposed that they denied the existence and perfections of God as such, nor that they denied that God is a “Father” in the relation which he sustains to the universe; but the meaning must be that what they held went to a practical denial of that which is special to the true God, considered as sustaining the relation of a Father to his Son Jesus Christ. Correct views of the Father could not be held without correct views of the Son; correct views of the Son could not be held without correct views of the Father. The doctrines respecting the Father and the Son were so connected that one could not be held without holding the other, and one could not be denied without denying the other. Compare the Matthew 11:27 note; John 5:23 note. No man can have just views of God the Father who has not right apprehensions of the Son. As a matter of fact in the world, people have right apprehensions of God only when they have correct views of the character of the Lord Jesus Christ.
