There is a handbook called "Duties and Blessings of the Priesthood." Ask your Bishop where you may get one.
-You are to be observant and willing to do the Lord's Will.
-You are to see that there is no iniquity in the church, like gossip.(this is often not fulfilled because it is "not considered your place" to make judgments concerning the sins and iniquities of others.)
-You are to strengthen and watch over the church by teaching and exhorting all to come unto Christ.
-You are to be assigned home teaching families which you will have direct stewardship over.
-You may administer the Sacrament by passing, preparing, or blessing the Sacrament.
-You may baptize under direction and authority from the Bishop.
-You may ordain other members to the Aaronic Priesthood under direction and authority from the Bishop.
-You are to assist the missionary effort.
-You are to Teach the ordinances and principles of the Gospel, or the doctrine by the Spirit.
-You are to first learn(know them and do your best to fulfill them) the duties, and doctrine for yourself and then strengthen others with your knowledge.
