What is your take on why people are fleeing the church?
I see emphasis from the bishops on social justice, which is a major tenant of Marxism. I see additional emphasis on income equality/inequality with no emphasis on the work ethic. I see nothing being done to admonish illegitimacy.
I could go on.
That's a question with a very long answer, I'll try to be brief. I believe the "collapse" started when Rome changed the rites surrounding the Sacraments. People had been led along believing that the Church never changes and then almost overnight everything was changed. Then (and this is where I put on my tin foil hat) homosexuals infiltrated the clergy in massive numbers and basically just destroyed everything from within.
It's a lot more complex than just that, but I think those two things contributed more than anything else. There was also the birth control kerfuffle, the people who were happy with the changes expected (and were led to expect) that the Church would change its teaching on birth control as well. There was a backlash when that didn't happen.
Because it's not Catholic enough.
Not serious about doctrine, not serious about discipline, not serious about being the Church Militant (while still having some of the characteristics of the Church Nurturant.)
If the Church made more demands at every level --- heroic truth, heroic service, the heroic attachment to Christ --- some slackers would leave but many men would be inspired and come back.
That's my take on it.
False ecumenism.
Some men left because they didn't want anyone to think they were molested. It was embarrassing.
