Gregory the Great

The Lord appeared to Abraham by the oaks of Mamre, as he sat at the entrance of his tent in the heat of the day. He looked up and saw three men standing near him. When he saw them, he ran from the tent entrance to meet them, and bowed down to the ground. He said, “My lord, if I find favor with you, do not pass by your servant. Let a little water be brought, and wash your feet, and rest yourselves under the tree. Let me bring a little bread, that you may refresh yourselves, and after that you may pass on—since you have come to your servant.” So they said, “Do as you have said.” And Abraham hastened into the tent to Sarah, and said, “Make ready quickly three measures of choice flour, knead it, and make cakes.” Abraham ran to the herd, and took a calf, tender and good, and gave it to the servant, who hastened to prepare it. Then he took curds and milk and the calf that he had prepared, and set it before them; and he stood by them under the tree while they ate.

They said to him, “Where is your wife Sarah?” And he said, “There, in the tent.” Then one said, “I will surely return to you in due season, and your wife Sarah shall have a son.” And Sarah was listening at the tent entrance behind him. Now Abraham and Sarah were old, advanced in age; it had ceased to be with Sarah after the manner of women. So Sarah laughed to herself, saying, “After I have grown old, and my husband is old, shall I have pleasure?” The Lord said to Abraham, “Why did Sarah laugh, and say, ‘Shall I indeed bear a child, now that I am old?’ Is anything too wonderful for the Lord? At the set time I will return to you, in due season, and Sarah shall have a son.” But Sarah denied, saying, “I did not laugh”; for she was afraid. He said, “Oh yes, you did laugh.”

1 Be joyful in God, all you lands; *
sing the glory of his Name;
sing the glory of his praise.

2 Say to God, "How awesome are your deeds! *
because of your great strength your enemies cringe before you.

3 All the earth bows down before you, *
sings to you, sings out your Name."

4 Come now and see the works of God, *
how wonderful he is in his doing toward all people.

5 He turned the sea into dry land,
so that they went through the water on foot, *
and there we rejoiced in him.

6 In his might he rules for ever;
his eyes keep watch over the nations; *
let no rebel rise up against him.

7 Bless our God, you peoples; *
make the voice of his praise to be heard;

8 Who holds our souls in life, *
and will not allow our feet to slip.

It is Christ whom we proclaim, warning everyone and teaching everyone in all wisdom, so that we may present everyone mature in Christ. For this I toil and struggle with all the energy that he powerfully inspires within me. For I want you to know how much I am struggling for you, and for those in Laodicea, and for all who have not seen me face to face. I want their hearts to be encouraged and united in love, so that they may have all the riches of assured understanding and have the knowledge of God’s mystery, that is, Christ himself, in whom are hidden all the treasures of wisdom and knowledge.
