Fulton J. Sheen said this quote

Most of us love a non-self, or something extrinsic and apart from our inner life; but a mother's love during the time she is a flesh-and-blood ciborium is not for a non-self but for one that is her very self, a perfect example of charity and love which hardly perceives a separation. Motherhood then becomes a kind of priesthood. She brings God to man by preparing the flesh in which the soul will be implanted; she brings man to God in offering the child back again to the Creator.
