Water Baptism not required for salvation,entry into body of Christ, but would be in obedience to Lord.By u asking that, it shows me that u don't understand the actual process.
The sign(baptism) and thing signified (salvation) are not one and the same. However, as I have shown in both confessions, it can be, if God so wills.
For example, how is it that both confessions say that in baptism, certain things occur, sometimes:
b)of being grafted into him,
c) of remission of sins,
Not everytime , i.e. 'not tied to the moment'. Meaning, God is not obligated to save a person during the baptism. But, He can, and does as He sees fit.
Does Christ forgive the sins of the unregenerate?
So, to answer directly; Baptismal regeneration is Reformed. BR, like Rome espouses, is aberrant.
