NCC 44 – What is Baptism?
Baptism is the washing with water in the name of the Father, the Son, and the Holy Spirit; it signifies and seals our adoption into Christ, our cleansing from sin, and our commitment to belong to the Lord and to his church.
NCC 43 – What are the Sacraments or Ordinances?
The sacraments or ordinances given by God and instituted by Christ, namely baptism and the Lord’s Supper, are visible signs and seals that we are bound together as a community of faith by his death and resurrection. By our use of them the Holy Spirit more fully declares and seals the promises of the gospel to us.
