We had several Nigerian priests and some Nigerian seminarians in Tulsa. Wonderful men, very spirit-filled, all seemed to come from large families. Charlotte has Vietnamese priests and seminarians, as well as other nationalities. They even found an Eritrean Catholic priest somewhere, to do Mass for our Eritreans.
I love seeing the variety of nationalities in the Church.
There can, however, sometimes be linguistic and cultural difficulties when you rely on this strategy.
Better to reform the seminaries, and restore the liturgy, IMO.
We are the mission now.
