Who said anything about supporting evil? Yes, the Church is infested, but so is everything else in this wicked world. The question is, “What is the Truth?” Was Jesus lying when He said that the gates of Hell shall never prevail against His Church? Notice, He said “prevail,” not “infiltrate.” There is a difference!
When time and money is given to an organization infested with evil, in which the common members have no means to reform it, that is supporting and enabling evil.
From your post it is evident that the evil extends thoroughout the leadership from the lowest rungs of the seminary clear to the Vaticant.
It appears that the only choices open to the lay member is to join with evil or go to hell. Great choice, there.
