Very true. Language is important, especially if you are interested in philosophical ideas or theological nuances.
I actually found my own religious foundation while learning the associated language. (that's a pun. The Egyptian ethical system is built around the key term of Ma'at, that can be abbreviated withe the glyph "ma", which visually and phonetically represents the base or pedestal of a throne. So if I say that Ma'at is the base of my ethics, that's a pun. But it does not show up to in translation)
on the other hand, I also find it fascinating to see the similarities. Think about it... translations are possible! Many words have pretty close equivalents in other languages. And if there is no direct translation, like with the different Greek variations of "love", you can still explain the concepts to an English speaker, using English words... You might just need a few more if them.
For me, it's comforting to know that people are not so different after all.
