The way I see it the Elders Council loses either way. If the Elders do chicken out (and that's very much over Constantine's dead body) then the Farronite-Niselur bloc will realise how strong their hand is and effectively veto any major Church decision that doesn't go their way. The Elders Council will lose much of its power and I doubt we will see any crusades in the near future. If the situation persists we may see the end of SA as a large powerblock.
SA only works if enough nobles are willing to voluntarily give their loyalty to the religion that the rest of the membership are too afraid of the religion to break free. The current conflict is the tipping point- if SA cannot subdue Niselur and co. then it does not have the power to enforce loyalty outside of the small number of characters who are willing to obey the Elders for purely rp reasons. If the balance does not tip back, SA could potentially become just like most other BM religions; a nice rp-point and forum for discussion, but not an organisation that can wield effective political power.
It will also make the accusations that SA will only pick on easy opponents like the 4vs1 on Aylson, or the pileup on Phantaria, seem true. I think Vellos's interpretation angle(and I may be wrong), might provide a graceful way out. I think I know where Vellos is going on this, but he is a very surprising man, and hard to read.
Oh and you are Consantine, your character seems pretty hardcore.
