So, I just finished RTI and though I feel like I followed most of it, there's still one thing that's kind of bothering me.

In the cutscene where the WOL uses the echo to see into the past, Delita is seen asking Orran to stay and work with him. Orran declines, saying that he doesn't want the church finding out about his history (presumably that he's been branded a heretic) to keep it from impacting Delita.

He is then later burned at the stake by the church.

I read up on some of the FF tactics lore, and what I don't get is this. After everything the church did, why did Delita allow it to remain as it was once he became king? It seemed like his intention was to double cross the church eventually, so why not take the opportunity to do it once it had been exposed that they were trying to summon Ultima?

I get that Orran was planning on the church essentially confiscating all of the copies of the durai papers, sequestering them away until it fell out of favor--but even so, surely Delita would have been able to intervene on behalf of Orran if he wanted to. For that matter, the XIV Delita says that he wanted Ramza to become his knight--something which the church would obviously have opposed due to his heretic status.

Was it just to try and consolidate power? Was it to try and keep the truth about Ramza from becoming exposed prematurely? I haven't really been able to find a satisfactory answer.
