I know of a young priest in India who has recently taken to Tradition. I also know some of the people who attend the TLM which he celebrates at his family home. But now I hear that a group in America has invited him to go over there and minister to them! So if he does run after the Almighty Dollar what will happen to those who attend his chapel? Will it not affect the very fragile Traditional Catholic movement in India? Does God bless this sort of behavior?
This is a complex and difficult issue. It's certainly not clear-cut.
On the one hand, sometimes God wants you to stay where you are planted. It is easiest for natives to convert/work with the population of a given country.
On the other hand, sometimes a country happens to produce more priests than it needs, relative to other countries.
In your example, it would be interesting to know the situation of the US chapel that is asking for that Indian priest. Are they in an area with little or no TLM options within a 3 hour drive? Or are they in California or Cincinnati, OH with 5 or 6 options within a half-hour drive, but they are extremely picky about various things (or even sectarian -- avoiding the Masses of this or that valid Trad priest)?
Remember, just saying, "I need the Mass" is ambiguous. There are a handful of sectarians (that is a better term than schismatic -- I will go into that later) in Danbury, CT who attend Fr. Pfeiffer's sporadic Masses there, and when he's not there, they stay home: from the local SSPX as well as Fr. Zendejas' Masses. Can they honestly say they "need" a TLM on most Sundays? I certainly don't feel sorry for them. They are in a borderline cult. Fr. Zendejas offers a valid TLM which is fully Traditional Catholic, and he is in full opposition to modernism, Vatican II, and the Novus Ordo. They don't have a leg to stand on.
That would make a big difference.
