Mother Church is nothing if not syncretic. You are welcome to come anytime.Despite, I'm not really Catholic. Unless Shinto Shaman Catholicism is actually a real thing.
I simply don't believe everything the church teaches. Also have a repugnance for many Catholics.
I like how I can walk into a Catholic church or the cathedral, stay for the service, receive the sacraments, and walk out of the church without anybody approaching me like at the Protestant services.
But it would be very disrespectful to take Communion. The priest won't do a background check first, but there are some rules on that subject and I am confident that you don't qualify.
Neither do I. So when I go up to Communion I bow my head and put my arms over my heart. I get a Blessing instead of Communion, and that works for me.
Way better than receiving Communion that I know I wouldn't get legitimately. Even though technically i do qualify. It's too much like stealing, I would rather not have have it, especially since I totally qualify for the Blessing. Absolutely everyone qualifies for the Blessings.
