if he says "i'm a christian in a way" in a context where christian is defined in a non-standard way that means he's only technically a christian in the context of that convo, but he doesn't believe god probably exists or jesus was resurrected or something, that would not be sufficient to resolve this market positively.

The market resolves YES if he converts to Christianity in a meaningful way, ie if the average person would look at his actions and would describe him as having converted to christianity.

Resolves NO in 2027 otherwise.
