Irenaeus quotes
He [Jesus] came to save all through himself; all, I say, who through him are reborn in God: infants, and children, and youths, and old men. Therefore he passed through every age, becoming an infant for infants, sanctifying infants; a child for children, sanctifying those who are of that age . . . [so that] he might be the perfect teacher in all things, perfect not only in respect to the setting forth of truth, perfect also in respect to relative age.
Irenaeus
For I have shown from the Scriptures, that no one of the sons of Adam is as to everything, and absolutely, called God, or named Lord. But that He is Himself in His own right, beyond all men who ever lived, God, and Lord, and King Eternal, and the Incarnate Word, proclaimed by all the prophets, the apostles, and by the Spirit Himself, may be seen by all who have attained to even a small portion of the truth. Now the Scriptures would not have testified these things of Him, if, like others, He had been a mere man.
Irenaeus
Esaias says: "The wolf also shall feed with the lamb, and the leopard shall take his rest with the kid; the calf also, and the bull, and the lion shall eat together; and a little boy shall lead them. ...” I am quite aware that some persons endeavour to refer these words to the case of savage men, both of different nations and various habits, who come to believe, and when they have believed, act in harmony with the righteous. But although this is [true] now with regard to some men coming from various nations to the harmony of the faith, nevertheless in the resurrection of the just [the words shall also apply] to those animals mentioned. For God is rich in all things. And it is right that when the creation is restored, all the animals should ... revert to the food originally given by God ... that is, the productions of the earth.
