Well if you’ll pardon my opinion, I think that hypothetical is pretty stale.
You can ‘only’ spend 100 million on one of two things? Seriously?
And of course one can ONLY be on a ‘physical’ help and the other ONLY a spiritual?
Catholicism is not an ‘either-or’ religion. It is a both-and.
We use our resources (money included) wisely.
There is no possible reason why money cannot be spent on a facility which works to heal and help with both spiritual (evangelization) AND physical (hospital) resources.
Trying to claim (and it’s only a claim, or opinion, never an actual truth) that Jesus would favor one method over another, especially one backed with ‘$100 million’ behind it is ludicrous.
Now if you want to ask, how can ‘I’ or ‘you’ or ‘others’ best help Jesus in His mission, that’s a really GOOD question (although I doubt any of us has $100 million). Some of us are fitted to help Him MORE at a given time through physical means, some through spiritual, but most through BOTH.
So maybe a person A can afford a few dollars a month to charity, spend a Saturday a month at a local soup kitchen, spend a weekday every other week to help out with religious education, say a family rosary with kids at home. A MIX of the above.
Maybe person B can afford a couple of hundred dollars a month to charity because he or she has a high paying job but the job itself keeps the person from going regularly to help out; but they also do family rosary. Still a mix, a little more $$, a little less physical presence, still spirituality.
Maybe person C is old and on a fixed income, but still physically hale. That person can go stand and pray at the local abortion center daily, go to daily Mass, help out through lots of time and prayer and presence, but has almost no money for charity.
Maybe person D is old, on a fixed income, and essentially bed or wheelchair bound. That person might ‘only’ be able to pray from his or her bed or chair. . . nobody might even be able to know or hear or see those prayers, but they are still just as helpful as anything from persons A, B, and C, etc.
I think it’s sad and silly to divide the world even more by getting people arguing over which response to WWJD be ‘better’, because money isn’t ‘better’ than prayer (nor is it ‘worse’) and hospitals aren’t better than evangelization (nor are they worse).
We don’t want to present a Christian as somebody forced to choose ‘the best’ and ignore the fact that for any given individual, ‘the best’ he or she is called to do might be different from some other individual, yet equally welcome.
