It might actually serve the church well for it to have a ritual of resignation. It could have several versions.
For those who leave the church but still respect it, there would be a means to turn in artifacts and icons, so that they would be treated with respect instead of thrown away or sold.
For those in contention with the church, they could be presented a document attesting that they are no longer Catholic, in case they are registered as such in other organizations. Likewise there would be a “records purge”, so they would no longer receive mailings or other communication from the church.
For those who now hate the church, a convenient way for them to leave online. And if they want, they can have a “no longer Catholic” letter mailed to them.
In a way, I have more respect for these lapsed Roman Catholics than for “Christians” who try to twist the Bible to say it supports things like homosexual behavior and abortion when it clearly does not.
As a point of information, the main Protestant denomination in the Netherlands, the mostly-Calvinist-but-a-little-bit-Lutheran PKN, permits individual congregations to decide whether to “bless” homosexual “unions”.
What’s the matter?
They can’t just stop going to church like others have done before?
This smacks more of drama-queen-ism than of simple rejection of a particular religion. But then it is the “gay” thing, isn’t it?
