From Circumcision to Baptism – Biblical Refutation of the Baptismal Views of Baptists and Anabaptists

Then, Noah and all his covenanted household were baptized by rainwater from above. However, the wicked outside the ark were non-baptismally drowned to death by total submersion from beneath.   Genesis 6:18 & 7:1-23 cf. First Peter 3:20f. 

Too, the Bible insists that adult believers like Abraham, after they had professed faith in Jehovah — were to be circumcised, covenantally, together with their (male) infants.   Then, drops of blood were shed — but there were no submersions!  

Thereafter, at Calvary — where also females of whatever age were elevated and given the sacrament (Acts 8:12 cf. Genesis 3:15f & 4:7) — covenantal circumcision was replaced by baptism (and hence infant circumcision by infant baptism).   Genesis 17:7-14; Acts 2:38f; Romans 4:11f; Colossians 2:11-13.
