Here are some of the major reasons the Church is failing:
1) Lack of Catholic Identity.
2) Intermarriage.
3) No nuns in Catholic schools to educate the children in the Faith and encourage boys into the  
priesthood and girls into the convent.
4) Small families; 1 or 2 children instead of 6-12 children.
5) Pedophile scandal and cover-up.
6) Our anti-religious/hedonistic/secular culture.
