I remember Fr. John Caulfield at BC High, where I got my Jesuit
vocation. I also remember Fr. Frederick Berigan and a scholastic,
Mr. John Galvin.
In 1947 I went to Georgetown to study astronomy. And it was there
that I got my PhD in astronomy in 1951.
Yes, it was often very chilly and even downright cold, but that
is often an astronomer's daily task. But you get lost in the splendors
of the sky and get used to the cold.
I chose astronomy, because I think it was a great help for the
work of the Church and especially in the modern day... Year later,
receiving the Pro Pontifice et Ecclesia award from Pope John Paul
II was thrilling and more than I deserved.
Your question-if I have sensed God's guiding hand-is very clear.
Answering it is another question. Yes. In many ways and at many
times, I have sensed God's guiding hand.
