Baptism and the Abrahamic Covenant

Q.        Isn't it quite a stretch to say that baptism in the New Testament is founded on some obscure covenant with Abraham which is buried in the pages of Genesis?

A.        Any such claims in this regard must be based upon an understanding of Scripture which can be clearly explained and solidly defended. The Scriptures are our only standard for faith and practice. We should not be so surprised to find a new Testament sacrament based on something in the Old Testament. The Lord's Supper, the other sacrament in Protestantism, is in a significant way founded on the Old Testament Passover. From a somewhat different angle, the Bible contains many combinations of people or concepts in the Old Testament which are directly related to people who fill roles or concepts which are more fully revealed in the New Testament.
