Many of the Fathers, such as St. Justin Martyr, saw Mary as the cause of salvation, at least in a sense that she gave birth to the Savior: the source of life because she is Mother of Life by cause of giving birth to Christ, her Saviour and ours.
Also, the adjective “holy” is prefixed to “Virgin.” Hippolytus, who was Greek in origin, mentality and language, states,
The words “holy” and “Virgin” were synonyms in Eastern thought. They thought of Mary as chaste, pure, and holy because of her virginity and mostly, her fiat (her “Yes” to God). As Eastern theologian Fr. Georges Florovsky said:
The dogma of I.C. developed more after the Council of Nicaea. We have St. Athanasius of Alexandria in the 4th century saying,
Athanasius also believed that Mary is a model of perfection. He states,
We also have the Greek Epiphanius and Ephraem in the Syriac speaking Church that lend us fresh insight into Mary’s sanctity. St. Epiphanius speaks of Mary’s womb as prepared for God as a temple and dwelling-place for the Lord’s Incarnation (
Panarion,
Haer). She was also “graced in every way”. He also calls her the holy vessel in which the Lord was carried:
However, Epiphanius had to be careful of his language. He did not want to put further emphasis on her holiness since there was the heresy of the Collyridians who actually worshipped Mary as a goddess, which the Church outright condemned. Anymore emphasis by Epiphanius might make it imply as if he was condoning the Collyridians. But he was clear that Mary still ought to be honored, but not adored.
We also have St. Ephraem’s witness which is more striking. He insisted that the Cherubim are not her equal in holiness, the Seraphim must yield to her loveliness, and the legions of angels are inferior to her purity (
Hymni de beata Maria, 13, nn. 5-6). He also praised Mary saying:
The stain is sin, and stainlessness is sinlessness; and so the text excludes from the Mother of God and from her Son all taint of sin, whatever it may be – consequently, even original sin.
But, alas, individual Fathers have no authority of their own. A view only carries wieght in light of the opinions of all the Fathers of Patristics as a whole. Good luck with your studies, Sandusky!
