“The Priesthood,” Friend, May 1986, 20
1 Several elders reported to Joseph Smith the success of their missions in the eastern states, and while they were together, the Prophet received a revelation concerning the priesthood.
2 Joseph was told that Adam was the first man on earth to hold the priesthood. The Lord then traced the line of priesthood authority back through some of the Old Testament prophets.
3 Only properly ordained priesthood holders have the authority to baptize, bless the sick, bestow the gift of the Holy Ghost, and administer the sacrament. When they exercise their priesthood righteously with humility, love, and kindness, the Holy Ghost will be their companion.
4 Missionaries were to preach the gospel to all the world, encouraging people to repent and baptizing them so that their sins would be forgiven and they could receive the Holy Ghost.
5 The Lord promised the missionaries that if they were faithful in proclaiming the gospel, all their needs would be provided for.
6 Joseph and the other brethren were grateful for the teachings from heaven about the priesthood, and they were eager to share its blessings with others.
