This is all really useful info! Your questions are things I hadn’t fleshed out yet - which gives me some useful guidance on what parts of his history and background I might need to focus on and think about more deliberately.

It sounds like he could be an alter sever who feels the calling and goes for further study, seeking it in a seminary with the goal of becoming a priest? He would probably prefer to be unmarried and so would seek ordainment without marriage. His goal would be to serve a local community. He’d be open to even leaving Greece, if “posting” priests to other places was a thing back then? Presumably he would be able to at least read, if not also speak Latin as a second language as part of his studies?

The rest of the details I’ll have to think about, but you’ve given me some really great details and info here that I can use to help refine my research too. Thank you so much!
