He would've played Stud-8 and just changed 7th street at will. Someone would've figured it out, and started a "Jesus Christ is a confirmed cheater and owes me money" thread on 2+2.
The poker community would've known that the "owed me money" part is BS because JC has been consistent with his attitude towards money lenders for 2000 years. Unfortunately, poker and Christianity take a huge hit when IFlopamonst22 and CYZXA15 on 2+2 perform a thorough hand history investigation and confirm that Jesus was in fact cheating by changing the 7th card to make the high and the low.
They post the hand history to 2+2 where JC gets lazy and forgets to divine everyone else's cards before changing his Ks on 7th street to a 2d, giving him a steel wheel. Someone else tables the 2d as well, and since local dealer Noah is dealing the game and his reputation for honesty and through was is impeccable, JC gets nabbed for the caper.
