You are still a Catholic and can come back at any time.
This I know, Salvation. I’ve always admired your sweet spirit, so, please do not be offended when I say that there are various reasons why I could not return to the Catholic Church, mostly because several major areas of their doctrine do not conform to the Scripture. If it was only minor areas (as is often the case with churches, denominational or non-denominational) and I believed attending would provide spiritual growth and maturity, I would not necessarily be opposed.
