Augustine of Hippo

"I write unto you, fathers." Why first sons? "Because your sins are forgiven you through His name," and ye are regenerated into a new life, therefore sons. Why fathers? "Because ye have known Him that is from the beginning:" for the beginning hath relation unto fatherhood. Christ new in flesh, but ancient in Godhead. How ancient think we? how many years old? Think we, of greater age than His mother? Assuredly of greater age than His mother, for "all things were made by Him." If all things, then did the Ancient make the very mother of whom the New should be born. Was He, think we, before His mother only? Yea, and before His mother's ancestors is His antiquity. The ancestor of His mother was Abraham; and the Lord saith, "Before Abraham I am." Before Abraham, say we? The heaven and earth, ere man was, were made. Before these was the Lord, nay rather also is. For right well He saith, not, Before Abraham I was, but, "Before Abraham I Am." For that of which one says, "was," is not; and that of which one says, "will be," is not yet: He knoweth not other than to be. As God, He knoweth "to be:" "was," and "will be," He knoweth not. It is one day there, but a day that is for ever and ever. That day yesterday and tomorrow do not set in the midst between them: for when the 'yesterday' is ended, the 'to-day' begins, to be finished by the coming 'tomorrow.' That one day there is a day without darkness, without night, without spaces, without measure, without hours. Call it what thou wilt: if thou wilt, it is a day; if thou wilt, a year; if thou wilt, years. For it is said of this same, "And thy years shall not fail." But when is it called a day? When it is said to the Lord, "To-day have I begotten Thee." From the eternal Father begotten, from eternity begotten, in eternity begotten: with no beginning, no bound, no space of breadth; because He is what is, because Himself is "He that Is." This His name He told to Moses: "Thou shalt say unto them, He that is hath sent me unto you." Why speak then of "before Abraham"? why, before Noe? why, before Adam? Hear the Scripture: "Before the day-star have I begotten Thee." In fine, before heaven and earth. Wherefore? Because "all things were made by Him, and without Him was nothing made." By this know ye the "fathers:" for they become fathers by acknowledging "That which is from the beginning."

"I write unto you, young men." There are sons, are fathers, are young men: sons, because begotten; fathers, because they acknowledge the Beginning; why young men? "Because ye have overcome the wicked one." In the sons, birth: in the fathers, antiquity: in the young men, strength. If the wicked one is "overcome" by the young men, he fights with us. Fights, but not conquers. Wherefore? Because we are strong, or because He is strong in us who in the hands of the persecutors was found weak? He hath made us strong, who resisted not His persecutors. "For He was crucified of weakness, but He liveth by the power of God."
