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.
There is always a way to clean up the Church: PRAYER!! and Fasting and Sacrifice. Just because no one has devised a program to do it, does not mean that Jesus can’t. We who are faithful are being called to suffer, and it is not for us to ask why, any more than we should ask why Jesus had to suffer for us on the Cross.
Rather than being evil Herself, I believe that the Church, the Bride of Christ, has been raped. It can’t be undone, but it can be healed and Christ can heal the Church, just as He heals us. It will take a lot of time and a lot of prayer and a lot of suffering, but in the end, the Bride of Christ will be glorious and spotless once again.
