I know they are pretty liberal, but if they are a part of your church your leadership should have some say in what they do.
I knew someone who was related to senior leadership, and a lot of them are pretty anti-Catholic.
If they are so "anti" why do they get away with using the name? It's a real lame argument to say that someone in your church "really isn't a member" when they do things that are wrong. We have the same problem with liberal Baptists and liberal Non-Denominational Christians. Typically they leave because they can't stand the heat.
I am not sure if any of the leadership is Catholic. The ones I know about weren’t.
Liberals have long wanted to take over the Catholic Church as they took over the Episcopal Church. Sr. Keehan is an example of this type of Catholic. Plus you have the temporizing kind like Fr. Jenkins.
