Holding on to your money doesn’t really send a message unless you explain to the pastor WHY you are withholding money. It’s too easy to assume it is because of the economy unless they know in no uncertain terms.
If your priest is one of those happy-clappy “spirit of Vatican 2” types, don’t be afraid to tell him where to get off. Find a conservative parish if possible, and support that church completely. Write your bishop, be a pain in the ass and encourage others to do the same.
The squeaky wheel get the grease.
