I appreciate your willingness to examine your faith.

To answer a previous question, the reason why you should always show goodwill towards everyone is to accept them where they are and try to convert them to the truth while keeping your heart open to recognizing the truth as well, wherever it may be (the Church doesn’t claim to be the only place of truth, just the fullness of truth).

Joe Heschmeyer posted a video recently titled The Biblical Case for Infallibility. Since you don’t claim goodwill towards Catholics, and you seem to have a strong resentment for anything a Catholic has to say about the Church, I don’t expect you to be open to his arguments. However, since you seem dedicated to Scripture, which is admirable, I hope you review the Bible passages he references and reflect on what God is trying to tell us.
