Okay, let's try this. Vatican II encourages discussion and dialogue with your separated brethrens. The Pope made a remarkable ecumenical statement of:
Pope Benedict said that Martin Luther’s doctrine of justification by faith alone is correct if ‘faith is not opposed to charity.’ The Pope said this during a general audience in a speech on St Paul’s teaching on justification. (Vatican, November 2008 - link)
Let's try again to have a mutual respectful discussion about our similarities and differences for the purpose of positive movement toward Christian unity. I don't think Catholic or Protestant apologetics impresses anyone on this site; therefore, let’s all try to refrain from posting apologetics which shuts down open and honest discussions. Instead, let’s have an honest respect discussion between Christian siblings who have the same Heavenly Father.
