Now I will speak of priesthood in the family. I begin with keys. The principle that priesthood authority can be exercised only under the direction of the one who holds the keys for that function is fundamental in the Church but does not apply to the exercise of priesthood authority in the family. A father who holds the priesthood presides in his family by the authority of the priesthood he holds. He has no need to have the direction or approval of priesthood keys in order to counsel the members of his family, hold family meetings, give priesthood blessings to his wife and children, or give healing blessings to family members or others.
If fathers would magnify their priesthood in their own family, it would further the mission of the Church as much as anything else they might do. Fathers who hold the Melchizedek Priesthood should keep the commandments so they will have the power of the priesthood to give blessings to their family members. Fathers should also cultivate loving family relationships so that family members will want to ask their fathers for blessings. And parents should encourage more priesthood blessings in the family.
