I remember my college Latin prof saying that if you ever wanted to feel good about your Latin skills you should read the Vulgate Bible. I've been working (very slowly) at translating it chapter by chapter (I'm up to Genesis 9). It does feel much more approachable than most Classical authors.

For learning classical Greek, I recommend beginning with a Biblical Greek text. In general the pedagogy from the Biblical people for Greek is so much better developed than what the classicists use.
