O GOD, who lovest all that is sincere and pure, and dwellest of Thy bountiful goodness in the chaste souls of the faithful: Purify us from all taint of sin, that we may always have our heart ready for Thee, and sing and play worthily unto Thee in Thy glory; through Jesus Christ, Thy Son, our Lord, who livest and reignest with the Father and the Holy Ghost, ever one God, world without end. Amen (Oremus, 1925, p.42).
