been a catholic all my life. I know they used to tell the parish a percentage to give but ive never heard that once in all of my adult life in any catholic church. Ive NEVER heard of ANY catholic church asking for tax info. If they did id be calling the bishop and complaining. I give what I feel I can afford and it varies week to week and its surely not even 5percent of my income. Bottom line is NO priest can tell you cant be a member unless you give X amount anyway so why even worry about it?
