ok, but if they are very similar in theology and the RCA is slightly less conservative than the PCA, what’s the (sorry for putting it in business terms) advantage for these three to join the PCA? Does it mean their theological stance is made more conservative or is it more like “we have similar if not the same beliefs, we should not be apart”?

I suspect these congregations were left behind when their previous denomination became more liberal and wanted to join a group that reflected their level of understanding on a liberal-conservative continuum. Hope that helps.
