The emphasis I placed in my last reflection on the harmfulness of false teachings is very necessary, for even today believers are confronted with erroneous teachings that have crept into the Church. I have written and spoken about this in my publications, and I invite you to read about the teachings and practices endangering the faithful in the Church today:

Heretical teachings, however, must be clearly rejected, which is usually done through the authority of the Church. The problem arises when the Church itself spreads errors or fails to correct them. Unfortunately, this is increasingly the case. Thus, the faithful must—hopefully with the help of some priests—reject these errors themselves based on the Catholic faith handed down through the ages.
