A sacrament is a sacred ceremony or ritual performed in a Christian church that is believed to have been instituted by Jesus Christ and is a sign or symbol of a spiritual reality.

The Roman Catholic Church recognizes seven sacraments: Baptism, Confirmation, Eucharist, Penance, Anointing of the Sick, Holy Orders, and Matrimony.

Baptism is a sacrament that cleanses a person from sin, initiates them into the Christian community, and marks them as a follower of Jesus Christ.

The Eucharist is a sacrament that is a memorial of the Last Supper, a means of grace, and a way to receive forgiveness of sins.

Confirmation is a sacrament that confirms a person's faith, strengthens their faith, and gives them the gifts of the Holy Spirit.

Sacraments are instituted by Jesus Christ, are visible signs of invisible grace, and are necessary for salvation, while ordinances are instituted by the church and are not necessary for salvation.

Marriage is an ordinance in Christian Law, while baptism, confirmation, and Eucharist are sacraments.

Marriage is a lifelong covenant between a man and a woman that is a means of procreation and a way to provide for and raise children.

Adultery, desertion, and cruelty are all grounds for divorce in Christian Law.

The sacrament of penance is a sacrament that forgives sins, reconciles a person with God, and restores them to the community of the faithful.

The sacrament of anointing of the sick is a sacrament that heals the sick, comforts the sick, and prepares the sick for death.

The sacrament of holy orders is a sacrament that ordains men to the priesthood, gives them the authority to celebrate the sacraments, and enables them to preach the Gospel.

The sacrament of matrimony is a sacrament that unites a man and a woman in marriage, creates a lifelong bond between them, and provides for the procreation and upbringing of children.

The essential elements of a valid marriage in Christian Law are the consent of the parties, the presence of a priest or deacon, and the exchange of vows.

Consanguinity, affinity, and disparity of cult are all impediments to marriage in Christian Law.
