According to the text, `We are the body of Christ and each of us is one of its members' (cf. 1 Cor. 12:27), we are said to be the body of Christ. We do not become this body through the loss of our own bodies; nor again because Christ's Body passes into us hypostatically or is divided into members; but rather because we conform to the likeness of the Lord's flesh by shaking off the corruption of sin. For just as Christ in His manhood was sinless by nature both in flesh and in soul, so we too who believe in Him, and have clothed ourselves in Him through the Spirit, can be without sin to Him if we so choose.
St. Maximus the Confessor, Second Century on Theology, Philokalia, V. 2
