The Church's Year
The Introit of this day's Mass, which begins with the word Laetare, is as follows:
INTROIT Rejoice, O Jerusalem, and come together all you that love her; rejoice with joy you that have been in sorrow: that you may exult, and be filled from the breasts of your consolation. (Isai: LXVI. 10. 11.) I rejoiced at the things that were said to me: We shall go into the house of the Lord. (Ps. CXXI. 1.) Glory be to the Father and to the Son, and to the Holy Ghost, as it was in the beginning, is now, and ever shall be, world without end. Amen.
COLLECT Grant, we beseech Thee, almighty God, that we who justly suffer for our deeds may be relieved by the consolation of Thy grace. Through our Lord Jesus Christ Thy Son, who liveth and reigneth with Thee, in the Unity of the Holy Ghost, God, world without end, Amen.
EPISTLE (Gat. IV. 22-31.) Brethren, it is written that Abraham had two sons; the one by a bond-woman and the other by a free-woman. But he who was of the bond-woman was born according to the flesh; but he of the free-woman was by promise: which things are said by an allegory. For these are the two testaments. The one from Mount Sina, engendering unto bondage, which is Agar: for Sina is a mountain in Arabia, which hath affinity to that Jerusalem which now is, and is in bondage with her children. But that Jerusalem which is above is free, which is our mother. For it is written: Rejoice, thou barren that bearest not: break forth and cry, thou that travailest not; for many are the children of the desolate, more than of her that hath a husband. Now we, brethren, as Isaac was, are the children of promise. But as then he that was born according to the flesh persecuted him that was after the spirit, so also it is now. But what saith the scripture? Cast out the bond-woman and her son: for the son of the bond-woman shall not be heir with the son of the free-woman. So, then, brethren, we are not the children of the bond-woman, but of the free: by the freedom wherewith Christ hath made us free.
EXPLANATION It was the common custom, in the days of the patriarchs, for a man to have more than one wife.
