Do you actually know what excommunication is?
Do you understand how it can occur?
I only ask because I see no indication that you do.
Let's take Hitler and Stalin:
Hitler was admonished by a priest as a teenager, went crying from the church and NEVER RETURNED (there is NOTHING to suggest that he ever went to mass again and he certainly didn't have a Catholic funeral). By his actions he would later excommunicate himself.
Stalin left the seminary and would later tell the world that he rejected the Church in favor of Marxism. His own actions would also later excommunicate him.
Wag I am always told I am still a Catholic and still under the authority of the catholic church because my Catholic baptism left an INDELIBLE mark on my soul.
How is that not true of them ??
