Q. 100. What is Baptism?
A. Baptism is an holy ordinance, wherein the washing with water in the name of the Father, the Son and the Holy Spirit, signifies our ingrafting into Christ and partaking of the benefits of the covenant of grace, and our engagement to be the Lord’s.
Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, Matthew 28:19
Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life.
For if we have been united with him in a death like his, we shall certainly be united with him in a resurrection like his. Romans 6:3-5
Having been buried with him in baptism, in which you were also raised with him through faith in the powerful working of God, who raised him from the dead. Colossians 2:12
For as many of you as were baptized into Christ have put on Christ.
