"It is not Christianity which causes problems, but the churches "

A good point. Obe of the main reasons that, while a Christian by birth, and remain so, I never closely associate with any one of these organizations.

But, actions take people-who are these people?

When it comes to the RC church (such in mostnof Ireland) , I recall Joe O indicating it is not the RC church members who control some of the bad aspects within this church. So, what/who is "this church"?
