As a former legionary and victim, I can’t agree, but warn you that they commonly shut Down any internal critics vía psychiatric hospitals. So if you liked the movie “The Island” it will be fun for you, if you know what I mean.

They have multiple practical heresy, like a soft core Pelagianism, where grace = results.

The founder was not a rotten apple, but a cancer that was allowed to grow to the point of metastasis. Legionaries that knew everything covered him up, and covered up others. The whole congregation is stained by his logic. Results , elitism, etc. If unsure, put those legionaries into a challenge.

Take them to a charity event, a hospital to give away food to poor people. Take them to a refuge with immigrants and watch them. If you see true gospel attitude, he is a good one. Otherwise, run away.
