His duty is to perform those prayerful duties delegated by the Master. Although Freemasonry is not a religion, Masons believe that a religious belief is important for a man. We do not care what religion a man believes in. Most every religion is represented somewhere in the Masonic Fraternity. We have a Chaplain in our officer core because we open and close each meeting with a secular prayer. The Chaplain is in charge of that duty.
