Yes, but don't forget that many of the Presbyterian USA congregations are also conservative True enough, but if anyone jumps from the Episcopal Church to the PCUSA, they are going to have to go through this again in a few years. If they are going to jump, they might as well go somewhere that is at least a generation away from this path.
In a few years? Presybterian USA is already going through this....... I wish I could tell you differently but we've been battling this for about 7 years now....... and losing.......but your words of caution are very true -
