How do Jack and Mark know each other? AFAIK Mark has not been in the show since the 90's

I wondered too, so looked up the character's wikipedia page and it says:
https://en.wikipedia.org/wiki/Mark_G...eligious_views

but it also sounds like he might have abandoned his faith after the coma, at least that's how I read 'comes to his senses'. But it probably is through the priesthood, or the congregation/administration at the church Jack went to.
