ALCUIN . Or, Hath put to his seal, i. e. hath put a seal on his heart, for a singular and special token, that this is the true God, Who suffered for the salvation of mankind.
AUGUSTINE . (Tr. xiv. c. 8) What is it, that God is true, except that God is true, and every man a liar? For no man can say what truth is, till he is enlightened by Him who cannot lie. God then is true, and Christ is God. Wouldest thou have proof? Hear His testimony, and thou wilt find it so. But if thou dost not yet understand God, thou hast not yet received His testimony. Christ then Himself is God the true, and God hath sent Him; God hath sent God, join both together; they are One God. For John saith, Whom God hath sent, to distinguish Christ from himself. What then, was not John himself sent by God? Yes; but mark what follows, For God giveth not the Spirit by measure unto Him. To men He giveth by measure, to His only Son He giveth not by measure. To one man is given by the Spirit the word of wisdom, to another the word of knowledge: one has one thing, another another; for measure implies a kind of division of gifts. But Christ did not receive by measure, though He gave by measure.
CHRYSOSTOM . (Hom. xxx. 2) By Spirit here is meant the operation of the Holy Spirit. He wishes to shew that all of us have received the operation of the Spirit by measure, but that Christ contains within Himself the whole operation of the Spirit. How then shall He be suspected, Who saith nothing, but what is from God, and the Spirit? For He makes no mention yet of God the Word, but rests His doctrine on the authority of the Father and the Spirit. For men knew that there was God, and knew that there was the Spirit, (although they had not right belief about His nature;) but that there was the Son they did not know.
AUGUSTINE . (Tr. xiv. c. 11) Having said of the Son, God giveth not the Spirit by measure unto Him; he adds, The Father loveth the Son, and farther adds, and hath given all things into His hand; in order to shew that the Father loveth the Son, in a peculiar sense. For the Father loveth John, and Paul, and yet hath not given all things into their hands. But the Father loveth the Son, as the Son, not as a master his servant: as an only, not as an adopted, Son. Wherefore He hath given all things into His hand; so that, as great as the Father is, so great is the Son; let us not think then that, because He hath deigned to send the Son, any one inferior to the Father has been sent.
THEOPHYLACT . The Father then hath given all things to the Son in respect of His divinity; of right, not of grace. Or; He hath given all things into His hand, in respect of His humanity: inasmuch as He is made Lord of all things that are in heaven, and that are in earth.
ALCUIN . And because all things are in His hand, the life everlasting is too: and therefore it follows, He that believeth on the Son hath everlasting life.
BEDE . We must understand here not a faith in words only, but a faith which is developed in works.
CHRYSOSTOM . (Hom. xxxi. 1) He means not here, that to believe on the Son is sufficient to gain everlasting life, for elsewhere He says, Not every one that saith unto Me, Lord, Lord, shall enter into the kingdom of heaven. (Matt. 7) And the blasphemy against the Holy Ghost is of itself sufficient to send into hell. But we must not think that even a right belief on Father, Son, and Holy Ghost, is sufficient for salvation; for we have need of a good life and conversation. Knowing then that the greater part are not moved so much by the promise of good, as by the threat of punishment, he concludes, But He that believeth not the Son, shall not see life; but the wrath of God abideth on him. See how He refers to the Father again, when He speaketh of punishment. He saith not, the wrath of the Son, though the Son is judge; but maketh the Father the judge, in order to alarm men more. And He does not say, in Him, but on Him, meaning that it will never depart from Him; and for the same reason He says, shall not see life, i. e. to shew that He did not mean only a temporary death.
AUGUSTINE . (Tr. xiv. c. 13) Nor does He say, The wrath of God cometh to him, but, abideth on him. For all who are born, are under the wrath of God, which the first Adam incurred. The Son of God came without sin, and was clothed with mortality: He died that thou mightest live. Whosoever then will not believe on the Son, on him abideth the wrath of God, of which the Apostle speaks, We were by nature the children of wrath. (Eph. 2:3)
