Immunize them in advance by telling them the truth. Unfortunately, we have been left with no choice in this period of diabolical disorientation but to point out to our children the widespread defections within the hierarchy (and the priesthood) from Traditional teachings. If we fail to do so, they will definately be in for a shock down the line.
THat makes a lot of sense, one thing that bothers me is I don't want to poison my children against the institutional Church. We've already had enough "Daddy says the Church teaches this but the bishop teaches otherwise" events. Balancing what we teach and what the Church appears to be teaching is a difficult job, on one side looms sedevacantism and on the other is the Church of Nice. Neither of those possibilities does anything other than scare me.
