This can be a big problem and there is little anyone can do about it, since the Church is for ALL men, when someone enters we must allow entrance.
Not sure where I heard this, but remember reading the Our Lady asked the Church to be careful who they allowed into the seminaries.
Remember they did it once, now they are running the Vatican, making Catholics look really bad in the eyes of the world, by their bad example.
What would stop them from doing it again to the remnant Catholics in the world.
