They were not ordained by Christ as necessary to salvation, but arose from the practices of the apostles and the Early Church, or were blessed by God in Scripture. God clearly uses them as means of grace.
Other rites and institutions commonly called sacraments include confirmation (2 Timothy 1:6–7; Hebrews 6:1–2), ordination (Numbers 8:9–14; 27:18–23; 1 Timothy 4:14), marriage (Genesis 2:18–24; Matthew 19:4–6; John 2:1–11), absolution ( John 20:21–23; Acts 2:37– 41), and the anointing of the sick ( James 5:14). These are sometimes called “sacraments of the Church.”
The two sacraments ordained by Christ that are “generally necessary to salvation” (1662 Catechism) are Baptism and Holy Communion (also called the Lord’s Supper or the Holy Eucharist). These are sometimes called “sacraments of the Gospel.”
I should receive the sacraments by faith in Christ, with repentance and thanksgiving. Faith in Christ is necessary to receive the grace of the sacraments, and obedience to Christ is necessary for the benefits of the sacraments to bear fruit in my life.
A sacrament is an outward and visible sign of an inward and spiritual grace. God gives us the sign as a means by which we receive that grace and as a tangible assurance that we do in fact receive it.
I should live in joyful expectation of the fullness of my transformation, soul and body, into the likeness of Christ. In the midst of suffering or in the face of hostility and persecution, I am sustained by the hope of a new heaven and earth, freed from Satan, evil, suffering, and death.
I know that it will be an eternal life of joyful fellowship with our triune God, together with all his saints and angels, singing his praises and serving him in the renewed creation.
Because I put my hope in God’s resurrection of my body, I should honor and care for it. I should refrain from any violence, disrespect, or sin that would harm, demean, or violate either my body or the bodies of others.
They will be fully renewed and glorified in the image of Christ, perfected after the manner of his own resurrected and ascended body.
