Here is one of the very best articles I've ever found presenting the credobaptist argument.

I think it also makes the point about "deduction" and the Regulative Principle of Worship much clearer than I did in my feeble attempts here in other threads.

We are all brethren and friends here, and I know several credobaptists who worship at Presbyterian churches (which are paedobaptist) because Reformed Baptist churches are so hard to find! And we are grateful that the Reformation has been preserved by those churches in which we find ourselves.
