Children are eligible for baptism on attaining the age of eight years, previous to which age they are not considered accountable before God for their transgressions.
No person who has been excommunicated from the Church can be re-admitted without repentance and baptism as at the first.
Baptism for the dead is administered in a similar manner to baptism for the living, a living person acting as proxy for the dead person on whose account the baptism is administered.
After baptism the candidates are confirmed members of the Church by the laying on of hands, that they may receive the Holy Ghost.
The duty of "every member of the Church of Christ having children, is to bring them unto the elders, before the Church, who are to lay their hands upon them in the name of Jesus Christ, and bless them in his name."
The laying on of hands is an ordinance also in the giving of patriarchal or other blessings to members of the Church, in ordination to office in the Priesthood, in setting persons apart to particular duties or callings or missions, and in administering to the sick in connection with anointing with consecrated oil and the prayer of faith.
In regard to the ordinance or sacrament of the Lord's Supper, the members of the Church are required to meet together often to partake of the bread and wine (or water, when pure home-made grape wine cannot be had) in remembrance of the Lord Jesus. An elder, a bishop or a priest can administer it. Usually the officer officiating breaks the bread into small pieces, kneels with the members of the Church assembled, and calls upon God, the Father, in solemn prayer, saying, "O God, the eternal Father, we ask thee in the name of thy Son, Jesus Christ, to bless and sanctify this bread to the souls of all those who partake of it, that they may eat in remembrance of the body of thy Son, and witness unto thee, O God, the eternal Father, that they are willing to take upon them the name of thy Son, and always remember him and keep his commandments which he has given them, that they may always have his Spirit to be with them. Amen."
After the members have partaken of the bread, the person officiating takes the cup and engages in prayer, saying, "O God, the eternal Father, we ask thee in the name of thy Son, Jesus Christ, to bless and sanctify this wine [or water] 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."
There is also the ordinance of marriage.
No person has authority to preach the Gospel, or administer in any ordinance thereof, unless he holds the Priesthood, and then to administer only in such ordinances as the particular office to which he has been ordained empowers him and often only by special calling and appointment.
