Their church's claim is basically Kousuke should be doing god-like thing for the people, otherwise why is he even a god.
Sylvia was not amused by that logic and question when the fuck did the church get to decide what gods do.
Since the clown tower master already made his piece, she question the temple head if that's REALLY what his church want to claim.
Then she ask the king of Gates, who's here at the table but as just 'part of the crew' if that's what his country is standing by. Even give him a warning that for the sake of his country, maybe cut ties with these two, alluding to another of the past hubristic country that angered the god.
King, unsurprisingly, did not heed the warning.
Sylvia "Well, I was hoping it wouldn't come to this, but these are the seeds you sowed"
i.e. You FA'd, now you must FO.
And voila, the divine communication tool, with Eris Jamil and Spica revealing themselves to have been listening in to the whole conversation.
The gods express their anger, especially at the church for twisting the previous oracle (ch 40) to their own benefit, AND this guy is a repeat offender.
So now they must all FO, though Eris told Kousuke to decide the punishment.
King try to beg for mercy, but Kousuke counter with if Kousuke goes easy on them, the gods will scold him instead.
So in order:
Against country of Gates - their fleet that's heading to this continent, pretending ot be pirates and previously attacked Crowns' ship? It's lazor time. Kousuke will at least give them some time to evacuate from the ship (Eris adding in that if it were the other gods they would've just nuke it with no warning)
Against Beckham tower - Amamiya will start a tower battle between them. During this state the towers entrance can't be closed and whoever conquer the other side win...(guess which pissed off angel will get to vent her anger, so in a sense you were right) oh but Kousuke's got 0 interest in managing a tower on a different continent so once he's taken the tower he'll just reset it back to the neutral, unconquered state. If Gates/Beckham want to use it again, feel free to re-conquer it just like their ancestors did.
Against the church - The gods will remove their blessings from the church and any associated with it. While this isn't as bad as them removing their blessings from the land itself that led an empire to ruin in the past (crop stop growing, monsters increase, etc) a church that has been rejected by the gods will probably not be treated well by any others.
And just to put extra nails in the coffins, the gods will personally descend to announce the details of this all over the world, so no more of that twisting the oracle bs.
