“There is no child of Mary except Jesus, according to the opinion of those who think correctly about her.”
Origen, Commentary on the Letter of the Romans 3, 10; PG 14, 956-57
“Those who speak thus means to safeguard Mary’s dignity in the virginity she conserved until the end, so that that body chosen to the Word, who said , “the Holy Spirit will come upon you and the power of the Most High will overshadow you” (Lk 1:35), did not know any relations with a man, after the point that the Holy Spirit came down upon her and the power of the Most High overshadowed her. I consider it to be in conformity with reason that, with regard to the purity which consists in chastity, Jesus was the first among men, while Mary was the first among women. It is the act of a wicked man to attribute the first place in virginity to anyone else.”
Origen, Commentary on Matthew 10,17; PG 13, 876-77; GCS 40,21-22
“Every incorrupt and virgin soul, having conceived by the Holy Spirit in order to give birth to the will of the Father, is a mother of Jesus.”
Origen, Fragments on Matthew 281; GCS 41/1, 126
