Around 2010 or so, I rented a pair of YA novels from my local library. They were the first two books in a superhero series (I don't recall if there were any more). The first book was a gameshow for young superheroes, I believe competing for the chance to become a sidekick to the host of the show. The gameshow eventually was revealed to be a plot of some kind.
The main character had the superpower to sever molecular bonds with his hands. There were several scenes where he would sit in his garage and carve marble statues for money on the side with his bare hands. His older brother was an established superhero. I remember the character was a churchgoer, Baptist or Methodist or something like that. He called some of the hymns "7-11's" (7 words repeated 11 times). Several scenes involved him talking to his youth pastor asking for advice. The cover was the main character with his costume, which was either a black or red hoodie obscuring his face.
Initially I thought this was book 1 of the Extraordinary Adventures of Ordinary Boy, but I'd only read them around the same time.
