[Shun doesn't have too much to add to what's already been said, especially the part about them being considered part of the old gods. He'd noticed that from the start, and it had always seemed odd.]

Considering how long the cult has been operating, and the fact that we first encountered them behind those "down with Amaterasu" flyers that were going around in the first months after the new gods arrive, it's pretty obvious they intend to overthrow the Heavens. They've also managed to get gods under their control, so it looks like they not only want to put new gods into power, but put new gods in who take commands from the cult's higher-ups.

[First with Votelli, now with Talos - there had been a pattern of gods deferring to the orders of high-ranking cult members.] They've been treating us as part of the old gods since the start, so their focus with "new gods" seems to really be entirely new gods who haven't encountered the Heavens before at all. Probably because they're easier to try and control.
