Epistle: Romans xi. 33-36

    Lesson from the Epistle of blessed Paul the Apostle to the Romans. O the depth of the riches of the wisdom and of the knowledge of God! How incomprehensible are His judgments, and how unsearchable His ways! For who hath known the mind of the Lord? Or who hath been His counselor? Or who hath first given to Him, and recompense shall be made him? For of Him, and by Him, and in Him, are all things: to Him be glory for ever. Amen.
