One of the speakers at the retreat that I attended this past Saturday was introduced as a psychologist. Taking the microphone himself, he clarified that he was not just a psychologist but a Catholic psychologist, and added "and that makes a big difference."
When I am asked about my job, I say that I am a mathematician. What if I were to add, "and I am a Catholic mathematician"? Would that make a big difference?
Or at the times when I mention that I would in an office, what if I were to add, "and I am a Catholic who works in an office"? Would that make any difference?
Unlike the field of psychology, where Catholic doctrine may make an explicit contribution, I do not know that any actual mathematical ideas can be characterized as "Catholic." (Am I overlooking any?) Therefore, in practice, I probably would not mention my Catholicism when mentioning my occupation.
But, even if the actual mathematics that I do is not influenced by my Catholicism, is the way in which I do that mathematics at all influenced by me being Catholic? To be a Catholic mathematician who works in an office, what would that mean?
