Replying here instead of the Arrests thread, since it was off-topic for that thread.
Over some. It’s an overstatement to say ‘all’ faithful outside the Empire fall under his authority.
“Recent additions” are converts and Reclaimed. How do you think they became recent additions? Now, of course, he’s not going around enslaving people or coercing them to convert, but that doesn’t mean his staff don’t have the goal of Reclaiming Minmatar. Spreading the faith is carrying out the Reclaiming. I would not call it a ‘sinister plot’, but convincing people to take up the faith, and administering to their needs, is his goal.
Now, of course, I value what he does, and would have appreciated having more access to formal Amarr religious structure in the Republic when I lived there. But for many Minmatar opposed to Amarr in the Republic, that will still be too much, as he is still converting, and still Reclaiming.
