Shine within our hearts, loving Master, the pure light of Your divine knowledge and open the eyes of our minds that we may comprehend the message of your Gospel. Instill in us, also, reverence for Your blessed commandments, so that having conquered sinful desires, we may pursue a spiritual life, thinking and doing all those things that are pleasing to You. For You, Christ our God, are the light of our souls and bodies, and to You we give glory together with Your Father who is without beginning and Your all holy, good, and life giving Spirit, now and forever and to the ages of ages. Amen.
