The Book of Moroni Chapter 5 Critique

Setting: The mode of administering the sacramental wine is set forth. About A.D. 401–421.
Verses 1-2: The manner of administering the wine—Behold, they took the cup, and said: O God, the Eternal Father, we ask thee, in the name of thy Son, Jesus Christ, to bless and sanctify this wine to the souls of all those who drink of it, that they may do it in remembrance of the blood of thy Son, which was shed for them; that they may witness unto thee, O God, the Eternal Father, that they do always remember him, that they may have his Spirit to be with them. Amen.
Note: The LDS church has made numerous changes. Wikipedia Encyclopedia.
1)    Weekly administration of the sacrament in the LDS Church did not begin until the 1850s. There is no revelation directly commanding the sacrament to be a weekly practice, but rather the custom developed and spread throughout the church over time.
2)    Until the late 1890s or early-20th century, the entire congregation kneeled during the sacramental prayers, consistent with D&C 20:76 and Moroni 4:2. Current practice requires that only the individual giving the prayer kneel.
3)    Deacons and teachers did not originally take part in the preparing or passing of the sacrament, a practice which was first adopted in 1898 and was widely implemented in the 1920s or 1930s. Previous reluctance to involve them was probably due to the following verse from the LDS Doctrine and Covenants: ″But neither teachers nor deacons have authority to baptize, administer the sacrament, or lay on hands″ (Doctrine and Covenants 20:58). The term "administer" has since been interpreted as referring to recitation of the sacrament prayer, which deacons and teachers are not given the authority to do.
4)    Individual water cups, instead of drinking from a common cup, were introduced in 1911.
5)    Passing the sacrament first to the presiding church authority was emphasized in 1946.
6)    In 1833, Smith received the revelation known as the Word of Wisdom, part of which prohibits the consumption of alcohol, with the exception of sacramental wine. Initially, the Word of Wisdom was treated as a recommendation, and the early Latter Day Saints would still drink alcohol on occasion. During the late-19th century, church leaders began to interpret the Word of Wisdom as a mandatory requirement for members. This increased respect for the Word of Wisdom, combined with other scriptures in Doctrine and Covenants led congregations to begin substituting water for the sacramental wine. The practice was officially adopted church-wide in 1912.
