The rebellion is quite good actually. There are many factors that led to it.

I've already posted the side of the exorcists. Other than that :
 * Traitors in league with Qlippoth inciting the rebellion. Strada and the alliance are well aware of it. That's why they were able to surprise Walburga.
 * Fucking Strada using the rebellion for the benefit of everyone. He's an awesome dude. Because of the rebellion he was able to:
 * Relieve the resentment of the exorcists. The rebellion is kinda like the sports day between the three factions.
 * Fix the fucking view of the church. They were against the help of the FAs and Devils even if it is for the better.
 * Was able to give a piece of the Holy Grail to the alliance. It can be seen as a "sorry" gift. Strada already has it because he already knew what will happen. He gave the piece so that DxD will have a fail safe when someone dies.
