Sorry to interject but it's important to remember that the default belief system of the protestant begins with a negative proposition. It's not that they are for Jesus but they are against the Catholic Church.
They can quote all the scripture they want about how in they're rebuking their Catholic brethren (when they even bother to acknowledge we're members of the Body of Christ and most of them cannot agree on that) with the truth of Sacred Scripture but we know that's a lie.
Which is why any response to your question will more than likely be some variation of, "Truth hurts. Suck it up." In the end there is no charity there. There is no love and that's how we know they are not of Christ.
Good points and I will bear this in mind from now on. Thanks!
