There are two sacraments ordained by Jesus Christ to be administered by the church: these are Baptism and the Lord’s Supper. These two sacraments might best be defined as an outward and visible sign of an inward and spiritual grace.
Baptism is connected with entrance into the new covenant community, while the Lord's Supper (sometimes called Communion) is connected with ongoing covenant renewal.
In the Lord's Supper, Christians remember Jesus' death in their place for their sins. In Baptism, Christians remember Jesus' resurrection in their place for their salvation and anticipated personal future resurrection.
Together, these two sacraments are simultaneously God’s pledge to us, they are divinely ordained means of grace, they are our public vows of submission to the once crucified and now resurrected Christ, and they anticipate His return and the consummation of all things.
