I would say probably yes. The biggest help is to have a working knowledge of Western philosophy, the Greeks anyway, specifically Plato and Aristotle. If you have successfully completed a handful of philosophy courses you can usually understand and learn from Christian theologians, Catholic or otherwise. This is because theology draws very heavily from philosophy, along with Church tradition and Sacred Scripture. Aquinas is probably one of the more demanding (but worth it); modern ones like Kierkegaard or Barth (don’t know him well at all) are difficult for me. Augustine, easy, piece of cake - ditto Luther. Early Church Fathers are pretty easy to understand too, again, speaking generally, though there are definitely exceptions. I get a lot more out of theology than math, that is for sure.
