Mother of Christ…

Thus the blessed Mother of Christ, knowing that she is the mother of all Christians by reason of this mystery, shows herself a mother by her care and loving attention. For her heart is not hardened against these children as if they were not her own; her womb carried a child once only, yet it remains ever fruitful, never ceasing to bring forth the fruits of her motherly compassion.
–Blessed Guerric of Igny (c. 1075-1157)

The Holy Virgin…

I have been amazed that some are utterly in doubt as to whether or not the Holy Virgin is able to be called the Mother of God. For if our Lord Jesus Christ is God, how should the Holy Virgin who bore him not be the Mother of God?
–Saint Cyril of Alexandria (378-444)
