The best weapon the simple pewsitter can have today is to know his/her Catechism. So says Archbishop Lefebvre:
"In the Church there is no law or jurisdiction which can impose on a Christian a diminution of his faith.
All the faithful can and should resist whatever interferes with their faith, supported by the catechism of
their childhood. If they are faced with an order putting their faith in danger of corruption, there is an
overriding duty to disobey." (Open Letter to Confused Catholics : Chapter 18 : para 9)
