You lost me. Christians are subject to all human failings, period.
Every Christian is but one facet in the body whole. Some are the hands, others the thoughts, feet and legs, but all too often the asshole in that body makes itself known.
I am not a Christian so any critique means nothing for only Christians can fix what is wrong with their church.
I will end with this, at the hight of European and American Imperialism, Christianity held sway and or had influence over every corner of the earth. Now Christianity no longer the force it once was. The bully does not like to be bullied.
