ALMIGHTY, Eternal God, through Whom that which is not beginneth to be, and that which is hidden is made manifest: Cleanse the folly of our hearts and purify us of those vices which are secret, so that we may be able to serve Thee, O Lord, with a pure mind; 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.51).
