not sure of what your looking for but I think it pretty much means what it says. I certainly couldn't sit here and in one little post solve this whole "Salvation by Baptism" issue. If I could then I'm sure the COC and many others would have to tear their churches down, lol! This debate is an age old one and one that I am afraid that will never be resolved this side of Glory. It really boils down to what one is been taught and is willing to believe. I personally do not believe that the whole of scripture in all of its proper context is teaching that Salvation comes through a formula of "any sorts" whether that be Baptism by water, the name Jesus only, the trinity, speaking in Tongues and so forth. Having said that I do believe that Baptism by water is a Christian right and that is what Peter was reffereing, "Can any man forbid". Since the Gentile believers had evidently received the Holy Spirit such as they had then the Jews nor anyone could not claim that they were not saved so they had that rite to be Baptized and show their conversion/faith in the finished work of Christ.

I could say more but hope that helps ya. If you want more just say so and I'll try to write a little more.

I might add that Acts depicts the very early beginnings of the church and not everyone including the Apostles had it all down yet. It took many years to learn, Remember that Paul had to with stand Peter to his face on one occasion because yes the Great Peter had messed some things up. Not everyone understood even the Apostles all of what the "Finished work" entailed or what the Grace and free favor of God really meant at the start of the early church. Also remember it was Paul that the mystery of the ages was revealed to. That was the famous "Christ in us the hope of Glory" scriptuer that Paul used.
