Catholics who renounce their church membership are barred from confession and communion, and from the anointing of the sick, unless they are on the point of death.Which begs the question; how does a priest know (in the confessional or the communion line or a large parish) that you have dropped membership? Does one have to wear a "666" tattooed on their foreheads?
LOL... but are you confusing that with Ash Wednesday?
The government supplies a report of who is “registered”, I suppose that would be yearly, after tax time.
