That one woman is both mother and virgin, not in spirit only but even in body. In spirit she is mother, not of our head, who is our Savior himself-of whom all, even she herself, are rightly called children of the bridegroom-but plainly she is the mother of us who are his members, because by love she has cooperated so that the faithful, who are the members of that head, might be born in the Church. In body, indeed, she is the Mother of that very head.
Saint AugustineIt is said that there is no salvation outside the Church. Who denies this? And therefore whatever things of the Church are had outside the Church do not avail unto salvation.
Saint AugustineGod will cleanse your sins if you yourself are dissatisfied with yourself and will keep on changing until you are perfect.
Saint Augustine
