This is normally strictly against the policy of the Brotherhood, as he is a religious leader, but he swore in to the Order and declared to abaondon his God in all acts for the Brotherhood short of the actual Assasinations. The leader of the Brotherhood at the time was leniant with his case, and explained that if it ever got to the point that the Cardinal had to perform an assasination, he could ask his God for the target to have a safe passage to the Beyond. This is interesting, as the Pieces of Eden and the understanding of the Capitoline Triad has proven that there is nothing beyond our one life. It is also interesting that the Pope ignored the wisdom that the Assasins had gained on the subject of religion. However, as the Pope only ever assasinated one target, during a Prayer ceremony, he was able to perform the assasination, then inconpicuously pray for the body. Again, this does appear to be abnormal, but it was nevertheless Gerrad's way.
