One thing that I wish the Catholic Church would do better is prosyletizing. Most of the heretical sects do it and rather effectively but not so much for us. Almost all Catholics are Catholics because of ethnicity, be their country of origin in Europe or who occupied the country as a colony. We do possess the true message of God and we should do a better job of spreading it to people.
Gievn that the Catholic Church is growing again, someone is doing something right.
I think prosyletizing has its merits, but I think many are drawn to Christ through the outward signs from his people...
