Been watching the thread for awhile now, and analyzing all the points made in accordance with the provided evidence. I agree with comicgyal here.
Also, I want to offer some food for thought regarding this slumbering Jubileus being ignorant of Rodin assumption. The fear of Rodin, which could also just mean respect when referring to Jubileus, as well as, the statement made about spheres &. ranking not correlating to strength but solely specializations.
A portion of it reads, "During his time in paradise, the angel Rodin was charged with the task of creation, responding to Divine Will with various masterpieces."
This was referenced earlier as a means to debunk Rodin's standing, but this alone can substantiate his status & abilities. "Responding to Divine Will", Jubileus herself is the embodiment of Divine Will, and since Father Rodin is the only known Angel to be in the same sphere as her - having the same halo but not being referred to as "dea" (ie. goddess), this outright implies he acted in accordance to her values and inherently holds a very strong connection to her down to his very nature.
Jubileus is the Creator, Rodin creates weapons in accordance to her will, contextually her will brings about destruction - Rodin's job thematically coincides with her very nature. He's never shown to be pressed in any physical confrontation outside of being thrashed by Bayonetta. There's also the fact that his weapons were stated to have literally turned the tides of battle in war when Angel's were outnumbered. Rodin uses only his fists - raw latent power - this naturally makes him leagues superior to the weapons he crafts, and the Angels below the sphere he and Jubileus reside in. When taking all of this, along with the two fights with Bayonetta into account, you can see that this does not inconvenience the power scaling by any means. He's consistently placed at a point less than or equal to Jubileus and Bayonetta, via lore and combat. To say he would be High 6-A at best isn't correct as he fodderizes every angel and demon that comes his way whenever he tags along or is in a cutscene.
Lastly, if you're unsure if he scales to fullpower Jubileus - which I don't think he does at all - he definitely should compare to the Jubileus we've seen. This was an incomplete manifestation powered solely by Balder, the Right Eye. This definitely doesn't mean he would beat this iteration of Jubileus either, I think it would comfortably place him beneath the likes of Bayonetta & Balder who are also relative, and are both very much needed to even bring about a full power Jubileus in the first place. If Rodin loses to Bayonetta consistently, he should logically be slightly below Balder, too.
It's already established Balder & Bayonetta aren't too far below the other God tiers because, they're consistently shown to go pound for pound with them whether they lose via scripted fights in the game, story cutscenes, being able to summon the likes of Omne & Sheba, so on and so forth. All in all, I believe the same logic can be used for Rodin in regards to the halo situation.
