Saying that "If the Church didn't specifically condemn something then it's to OK hold or even do" isn't very logical.
Jehanne wants things to be be condemned that are not condemned (and may never be.) Until they are condemned, he must be at peace with his fellow Catholics.
The Church has not condemned the Neocatechumenal heresy and may never condemn it for the objective of the new Rome is to keep unity at all costs, even if this "unity" means the destruction of our Creed/Faith. Think of this when you receive communion, that Rome has turned our act of communion into a farse, for with the approval and full backing of Rome we commune with heresy. Yea, be "at peace".
