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 of LyonsNo man can know God unless God has taught him; that is to say, that without God, God cannot be known.
Irenaeus of LyonsSince it is impossible, without God, to come to knowledge of God, he teaches men through his Word to know God.
Irenaeus of LyonsThe glory of God is a human being fully alive; and to be alive consists in beholding God.
Irenaeus of Lyons
