Not religious nor an expert on this, but as far as I know:
“Taking the Lord’s Name in Vain” is the technical term in Christianity for using words that refer to God/Jesus in any context that isn’t directly referring to them, which is considered a form of blasphemy. The majority of Christians, Catholics especially, believe that even expressions like “oh my god!” or exclaiming “Jesus!” when surprised constitute taking the Lord’s name in vain, or as is what is happening here, where you use Jesus for something unrelated to him. And the bible does make it very clear that blasphemy is worse than literally any other sin.
is it? I checked the dictionary and it doesn’t seem like they’re doing anything in vain. https://www.merriam-webster.com/dictionary/vain
it’s literally the opposite of pride. they’re using his name to hide something they’re ashamed of
also the opposite, they’re trying to use his name in an effective manner to solve a problem
same as the previous, it would have a worth to them
again, they’re using it for schoolwork, which is educated, not foolish
