A kid named Jack who comes from a devout mormon family who all wear the infamous Magic Underwear starts going to kindergarten and starts getting bullied and after that he starts questioning his faith.

I recommend to write some logline guides, this is the one I prefere: http://www.raindance.org/10-tips-for-writing-loglines/ but you have one right on this site https://loglines.org/howto/

You'll understand why you can avoid character's names.

Anyway, I have no Idea of what a magic underwear is so I recommend to include more details in the logline. Then focus about the main character, his goal, his enemies.

Good luck!

The story feels ambiguous to me as mention of the magic underwear suggests a bit of surrealism injected into an otherwise real story and I'm not clear if that is your intention or not. Therefore, I don't get a sense of what the story will achieve.

When bullied at school for his Mormon faith, a young boy questions his faith by rebelling only to learn his magic underwear really is magic and gives him super powers that help him deal with the bullies.

A point of contention: I wonder if a 6-year-old would have the intelligence and awareness to question his faith. Perhaps your hero could be older?
