Of Adam and Christ

"If any of us does not recognize that he is Adam, the one who sinned before God in Paradise, how can he recognize and think that the coming down of the Son and Word of God was for him. A law was established after the Fall, that just as each of us is Adam, that is, corruptible and mortal man, not by reason of our own sin, but by reason of the disobedience of our first ancestor Adam, from whose seed we come; so each of us is of Christ, immortal and incorrupt, not for the sake of our own virtues, but for the sake of the obedience of the second Adam, Who is Christ our Lord Who came down from Heaven; we become bone of His bone and flesh of His flesh. And just as corruption and death come down from generation to generation from the old Adam, so also incorruption and immortality come down to Christians from the new Adam."

St. Symeon the New Theologian, Homily 38
