O Christ our Lord, who art the Physician of salvation, grant unto all who are sick the aid of heavenly healing. Look upon all faithful people who are sick and who love to call upon Thy name, and take their souls into Thy keeping, and vouchsafe to deliver them from all sickness and infirmity; through Jesus Christ. Amen.
