     For the Eve of the Assumption. From the Holy Gospel according to Luke Luke 11:17-28 At that time As Jesus spake unto multitudes, a certain woman of the company lifted up her voice, and said unto Him Blessed is the womb that bare thee. And so on. Homily by StAugustine, Bishop of Hippo. 10th Tract on John. Blessed is the Virgin Mary, because she did the will of the Father. Matth. xii. 50. This it was that the Lord praised in her, namely, that she did the will of His Father, not that her flesh had given birth to His Flesh. Be kind enough to give me your attention, my dear brethren. When the Lord amazed the crowd by working signs and wonders, and showing thereby What was veiled in His Flesh, a woman, in the astonishment of her mind, cried out Blessed is the womb that bare thee, and the paps which Thou hast sucked. But He said Yea, rather, blessed are they that hear the Word of God, and keep it. That is to say Even My Mother, whom ye call blessed, hath her blessedness from this, that she keepeth the word of God not because it was in her that the Word of God was made Flesh, and dwelt among us, but because she heareth and keepeth that Word of God by Which she was made, John i. 3, and Which in her was made Flesh.
