Laymen, get a copy of the Code of Canon Law.
Read it and know it. Know the rules. Know your rights.
As a high school student I worked for a millionaire and one day he called to complain that his water bed at home had broken. Myself and a colleague were asked to go to his manse to attempt to fix it.
His wife met us at the door and brought us into the bedroom. The first thing we saw were Canon Law books at his bedside. As a hobby he studied Canon Law. This is an inspiration. Be inspired.
