I was born and raised Roman Catholic and in 2001 I converted to the Orthodox Church. This year I returned to the Catholic Church via Confession.
Before doing so, I spoke to a friend who is a devout Catholic. He told me that he spoke to a canon lawyer about my return and he said all that was required was Confession.
However, after reading Canon 1364 section 1, it seems that I fell under automatic excommunication which can only be lifted by the bishop. Is this correct?
