Is the guy a ɧoɱosɛҳųαƖ, he is to be avoided. Give a clear warning.
People here do not care if a Novus Ordo bishop or Bergolio tells us to avoid a trad priest, that is not enough, as all the Novus Ordo bishops and Bergolio are not Catholics orthodox in belief and it is they that we avoid.
Unless you are some version of sedevecanti, you can't reject everything coming out Rome because not all of it is bad.
The only reason to avoid a priest is if he is a pervert? I can think of many other reasons as well. Consider that even though urrutigoity is a definite pervert, he has not been laicised. How bad does one have to be to be laicised??? Pretty bad...
And to have a "Good friend" be tetherow?
In my book, those are enough to want to stay away. I would not risk my soul or my children to such a man.
Do what you will.
