Man has been naturally so created that it is advantageous for him to be submissive, but disastrous for him to follow his own will, and not the will of his creator.
Saint Augustine... at the beginning of the human race the woman was made of a rib taken from the side of the man while he slept; for it seemed fit that even then Christ and His Church should be foreshadowed in this event. For that sleep of the man was the death of Christ, whose side, as He hung lifeless upon the Cross, was pierced with a spear, and there flowed from it blood and water, and these we know to be the sacraments by which the Church is built up.
Saint AugustineFor I wondered that others, subject to death, did live, since he whom I loved, as if he should never die, was dead; and I wondered yet more that myself, who was to him a second self, could live, he being dead. Well said one of his friend, "Thou half of my soul"; for I felt that my soul and his soul were "one soul in two bodies": and therefore was my life a horror to me, because I would not live halved. And therefore perchance I feared to die, lest he whom I had much loved should die wholly.
