Anyone on here learned a language for religion?

I learnt Arabic to read the Koran just for my interest's sake.

Sounds like my resume.

I studied Koine and Septuagint Greek (along with Homer and Attic), and I am working on Hebrew right now. I studied enough Latin to find my way around the Vulgate, but I have a long way to go on that one.

I learned enough Hebrew to hang in there for Shabbat services when I worked as music director at a reformed congretation.

Learned enough Latin to handle the Mass.

I'm Hindu and we have several Holy texts. They're all in Sanskrit (ancient Indian language, English is derived from Sanskrit). I don't know Sanskrit fluently, but all of our chants and prayers are in this language. I have the English translations so I know what I am chanting.

Still learning. Forever learning. Hebrew mostly, but Greek too...

I had to learn Hebrew as a child, but more recently (by choice,) I learned Welsh to aid my studies of Celtic Druidism.

I tried to learn Spanish but I didn't get too far. This preacher I know spoke Spanish and he was a missionary in Latin America. But I do well to know English.

I am learning Arabic for my prayers as a Muslim. I have learned enough to pray confidently in Arabic and I have committed to memory 5 surahs (chapters)

Insha Allah (Allah willing) I will learn more.

I took Biblical Hebrew in college. But I'm an atheist, so I don't know if that counts....

Cantonese Chinese...

...Well, as far as that goes, I think I understand the 'Tao Te Ching' a little bit less every time I try to read it. Bizarre thing...
