Repeatedly invoking the blessings of the Lord on behalf of our loved ones would be an expression of faith rather than a lack of faith.
In 1908 the First Presidency of the Mormon Church defined minimum ages for the Aaronic Priesthood in the Mormon Church to be 12 years for Deacons, 15 years for Teachers and 18 years for Priests.
Those holding the priesthood may, upon authorization, ordain other to the same priesthood held by the officiator or to any other lower priesthood office.
The restoration of the Gospel of Jesus Christ required the transfer of keys of priesthood authority from those who held them in earlier dispensations to Joseph Smith and Oliver Cowdery.
The Mormon practice of a Personal Priesthood Interview is to allow home teachers to counsel with their piresthood leader on any concerns they may have for those they home teach.
The keys to the ministering of angels are evident when a holder of the Aaronic Priesthood receives Divine help in answer to prayer. Also, those who are righteous, with their sins forgiven through their baptism by the Aaronic Priesthood, would qualify for the ministering of angels.
In the Mormon Church, baptism and the sacrament are administered through the Aaronic Priesthood. The ministering of angels is connected to these ordinances.
The priesthood in the Mormon Church is not designed to rule. Mormon women, still equal, do not hold the priesthood because their duties are elsewhere.
