The Highway Forums General Discussion Theology Discussion Forum Main Differences Between Reformed Baptists and Presbytarians?

Before answering this, we will have to make some definitions. What is meant by Reformed Baptist? I mean some puts those like John MacArthur as a Reformed Baptist, but he is only a Calvinist in his soteriology only, not in Covenant theology or ecclesiology, In order to be a Reformed Baptist when comparing with Presbyterians, is only baptism acceptable as being the only difference?
