I have never heard of such a fee in an American Catholic Church, but I have been out of it for many years. But I can see them doing it, since Catholics no longer go to church except for those things, and thus have stopped tithing long ago. It has gotten so bad in Germany, that they are excommunicating Catholics, who do not acknowledge being Catholic to avoid paying the annual tithe, which in that country is added to the income tax. In Delaware, many Catholics will not tithe unless they are assured the money is not going to the diocese, which is now bankrupt because of child abuse lawsuits; such a note is attached to the bulletin during annual appeals.
You know, if you come to Jesus, it does not matter what church you are in.
