Section 27: The Priesthood — Aaronic and Melchizedek

LDS theology holds that two levels of priesthood authority were restored to Joseph Smith: the Aaronic priesthood, restored by John the Baptist (May 1829), and the Melchizedek priesthood, restored by Peter, James, and John (June 1829). These priesthoods are the authority by which all valid ordinances are performed. No baptism, confirmation, sacrament, endowment, or sealing is valid without being performed by someone holding proper priesthood authority — which exists only in the LDS church.

Young men are typically ordained to the Aaronic priesthood at twelve (as a deacon) and advance through teacher and priest. Men receive the Melchizedek priesthood as young adults, typically around the time of their temple endowment and missionary service. Women do not hold the priesthood, a point of significant internal tension in contemporary LDS culture. Women's spiritual authority in the church is channeled through the Relief Society, Young Women, and Primary organizations.

"But because Jesus lives forever, he has a permanent priesthood. Therefore he is able to save completely those who come to God through him."

— Hebrews 7:24–25

ERROR IDENTIFIED: The Melchizedek priesthood's significance in the New Testament is precisely that it belongs permanently and exclusively to Jesus, not to an institution on earth. Hebrews' entire argument is that the Levitical priesthood system was replaced — not reformed, not continued through restoration, but replaced — by Jesus's permanent high priesthood. The claim to have restored the Melchizedek priesthood to earth is the claim to have un-done what Hebrews says Christ accomplished definitively. It requires a church institution to mediate what Hebrews says needs no earthly mediator.

Section 28: Sunday Worship — Sacrament Meeting

Weekly Sunday worship in a ward centers on Sacrament Meeting, which typically lasts one hour. The sacrament (communion) is administered by Aaronic priesthood holders: the bread and water (not wine — water has been used since 1912) are blessed by a priest and passed through the congregation by deacons. The sacrament prayers are specific, scripted texts from D&C 20 and must be recited exactly correctly; errors require the prayer to be repeated. The theological significance of the sacrament is as a renewal of baptismal covenants, not a participation in Christ's body and blood in any sacramental sense.

The bulk of Sacrament Meeting consists of lay member talks (sermons) on assigned topics, with congregational hymn singing. There is no professional liturgical leadership. The meeting is open to anyone, member or non-member, and it represents the public face of LDS worship — warm, family-oriented, deeply communal. What it does not present is what happens in the temple, which is the theological center of the system.
