Ok, the history founding of the church is solid. The church has also been under attack by evil since its beginning.
The current question is, has the smoke of corruption reached a critical mass of the men supposedly keeping the keys?
The smoke of corruption has certainly made it to the level of cardinal. (See cardinal law if you doubt this.)
The church needs to truly clean house. It should have zero tolerance for pedophiles, or those that enable them. Immediate excommunication for each, with a referral to the DA.
Do not confuse doctrine with the the lives of individuals. The Church IS cleaning house. But we have evangelical pastors who have murdered their wives and lovers.
