“For, if she had had other children, the saviour would not have ignored them and entrusted His Mother to someone else; nor would she have become someone else’s mother. She would not have [abandoned her own] to live with others, knowing well that it ill becomes [a woman] to abandon her husband or her children. But, since she was a virgin and was his mother, he gave her as a mother to his disciple, even though she was not really John’s mother, because of his great purity of understanding and because of her untouched virginity.”
Athanasius, De virginitate, in Le Musèon 42: 243-44
