Neither your post here nor your blog (which your link points to) provides any evdience to back up your statement that "Most believers say that the Pope is 'not a true Christian leader'".
I happen to be a Protestant.
I think the Pope is a Christian leader. (He is, after all, the Head of the Roman Catholic Church -- and is, I think, the leader of many, many people).
And I think the Pope is a Christian.
I (and, I would guess, most other Protestants) do not consider the Pope to be THE Christian leader.
Did you actually read the blog post? The headline was pulled directly from the article that appeared at Catholic Herald and was linked to directly in the body of the blog post. They said it, well, actually the survey they reported on said it...not me.
Blessings and Peace. KB
I think most of us feel that way. Thanks.
