22 Then after you have partaken of the Body of Christ, draw near also to the Cup of His Blood; not stretching forth your hands, but bending, and saying with an air of worship and reverence, Amen, hallow yourself by partaking also of the Blood of Christ. And while the moisture is still upon your lips, touch it with your hands, and hallow your eyes and brow and the other organs of sense. Then wait for the prayer, and give thanks unto God, who has accounted you worthy of so great mysteries.
