Christ said so. That is good enough for me.
I am am sorry you have issues with the Church. The Church hierarchy isn’t perfect and has much to atone for. I almost left the Church over the abuse crisis. I then decided that I wasn’t going to let evil drive me from the Church. So, I got involved in drafting the investigation protocol.
Clearly, it isn’t for you. To ridicule it as a cult denigrates it’s faithful. You are welcome anytime.
