When we as Catholics invite you to our Church we are not asking you to commit sin. We are not asking you to do anything which would violate your conscience. As a logical Protestant you must admit that one church is as good as another. This is based on private judgment, the fundamental doctrine of Protestantism. Every Protestant MUST ADMIT that every other person is just as correct as he is, and has the same right to worship God in any way he chooses. This would mean that the Catholic Church, too, is as good as any other Church; and there would be no guilt attached to attendance at a Catholic Church.

On the other hand Catholics believe that Christ decided what form of worship He wanted. He was God and had the right to say that He would be worshipped in this way or that way. We believe that He established only ONE form of worship, and intended us to participate in THAT FORM.

We are not free to say we would rather do it OUR way. Therefore for a Catholic to participate in any other form of worship would be a violation of his conscience; and this means sin. Therefore, when you invite us (in all good faith) to worship with you, you are in effect asking us to commit sin. We, of course, know this is not your intention.

Catholics are, however, permitted to participate with non-Catholics in services such as marriages, funerals, etc.
