A friend directed me to this quote. I’m not sure if there are different versions of it, but I’ll keep looking. This one is from Thomas Taylor’s translation of Story of a Soul from Project Gutenberg

“In Heaven only shall we be in possession of the clear truth. On
earth, even in matters of Holy Scripture, our vision is dim. It
distresses me to see the differences in its translations, and had
I been a Priest I would have learned Hebrew, so as to read the
Word of God as He deigned to utter it in human speech.”

-St. Therese of Lisieux
