In its countless divine services dedicated to the Mother of God, the Holy Orthodox Church firmly and clearly teaches the absolute sinlessness of Mary in her birth, her holy childhood and adolescence, in the Annunciation, in the birth of her Son and throughout her entire life. We shall pause at only the most important dogmatic witnesses borrowed from the services of Theotokos feasts. As is evident from these witnesses, the Most Holy Virgin is called in her very birth “Holy of Holies,” “living heaven,” “temple of all kings and thrones,” “sole immaculate one,” “the true temple pure from infancy on,” “hostile to the course of sin,” etc. The question arises: is the idea of any sort of assault of sin, which even some fathers of the church, and with them other orthodox theologians, allow, compatible with this veneration? Obviously not. The Mother of God was sinless, not a single attack of sin approached her most pure soul, the bearer of perfect virginity. But in that case is she not made equal “to the one sinless” Lord Jesus? No, and therein is the whole point. Sinlessness belongs in a unique and exclusive sense to the Son of God conceived without seed from a virgin who had never known a man, in that He was a stranger not only to every personal sin but also to original sin. The latter had absolutely no power over the new Adam. … It is quite the opposite in the case of the Most Pure and Immaculate One: in her, original sin preserved its entire power with all its fatal consequences–weakness and mortality of the body (for death is only the final revelation of this weakness). The Theotokos died a natural death in fulfilment of the natural law, which she bore in her human nature. Death was defeated only by the salvific power of Christ’s resurrection and was ultimately annulled by it. The Lord Jesus is in this sense the Saviour for the entire human race, and in it of His mother as well.
