Latin Everyday

I am fascinated by Roman mythology and how it relates to the language of Latin. Cupid comes from the verb cupio, cupere, meaning to want. Cupid makes you want someone. This is all I could find on this subject, but that got me thinking. What all have we gotten from latin in our own religion, Christianity. Lucifer comes from the words "lux", meaning light and "ferre", meaning to bring. Lucifer means "to bring light", which makes sense because he is the morning star. It can also be seen as how he convinced Adam and Eve to consume the fruit of knowledge, so he brought them knowledge, bring light to the darkness of not knowing. He brought the light to a shadow mind, but he is not a good guy.
