Sorry for my English, it’s not my native language. I’m reading the Vulgata, but I have no means of comparason to know if the Vulgata can be considered difficult or not. What is your opinion?
I guess it will vary a lot, depending a lot on each individual.
Assuming that most people learn (some) Classical Latin before, the Vulgate would certainly feel easier than most classical authors, if only because of the shorter sentences and possibly also because of their familiarity with the content.
On the other end, some aspects of grammar and vocabulary could take some time getting used to.
