If you weren’t interested in pursuing a degree in theology, I would say it’d be a waste of your time. However, I would say that Latin is very important to know for a person pursuing a degree in theology because of the reason posted above.
I agree, however…
It depends what kind of theology degree you intend on pursuing. If it’s a Sacred Theology Degree, you will need to be able to function in it. Ditto with Canon Law.
However if it’s not specifically
Sacred Theology, then no.
I have a theology degree with my Bachelor’s of Arts, and I have studied Latin in my spare time, and Latin hasn’t helped it much except for trivial bits here and there.
One of my professors had a Master’s of Divinity, is a priest and was the Provincial for his Order. Yet he never studied Latin. I don’t think my local bishop did either, except to do the Latin Mass. The reality is that it’s not very practical to learn in today’s Church anymore.
So unless if it’s specifically for
Sacred Theology or Canon Law (both of which you can’t even take till you’ve already gotten your four year degree; a bachelor of Sacred Theology is actually a graduate degree), don’t bother taking those classes in Latin.
Latin is a very tough language, you’ll be surprised, even after years of studying it you will not be proficient. Studying Spanish had more practical applications in the US. Italian is more practical too.
The reality is that even Cardinals don’t all understand Latin well, by their own admission.
So I’d discourage it, based on personal experience and the people I know who even have important Church positions.
