The "messages" and other related propaganda contain statements which, among other things, are contrary to the teachings of the Catholic Church, undermine the legitimate authority of bishops and councils and instill doubts in the minds of the faithful, for example, by claiming that, for years, an "imposter (sic) Pope" governed the Catholic Church in place of Paul VI.
