a primordial serpent visited the heavenly daughter Gertrude as an angel and taught her divine pillars of light, which became the foundation of the angelic religion within the kingdom. this religion led to the coup within the kingdom that culminated in the prince refusing to link the flame.
divine "angel" motif can be found from:
1. statue of primordial serpent
2. Gertrude cage
3. lothric boss room
4. winged knights (including painting)
5. oceiros' wings
6. divine pillar of light effect
7. rosaria man-grub divine magic & effect
8. ringed city angel magic & effect
there is a very secure link between the "divine" religion and the way of white, thanks to rosaria's fingers.
the founder of rosaria's fingers was klimt, an archdeacon of the cathedral of the deep. Klimt found rosaria, and chose to worship her as a goddess, relinquishing his saint's bident and making his sacred seal the symbol of his covenant. rosaria's maggots, as a result, wield staves bearing his sacred seal and cast divine magic depicting the saint's bident.
now why is an archdeacon of the cathedral of the deep using a saint's bident, and teaching divine magic? It goes back to the fact that Aldrich was originally a cleric, of the way of white. He developed a penchant for devouring people, which led to a religious following that splintered into its own cult, culminating with the cathedral of the deep. the cathedral is a perversion of the way of white, using their religious artifacts and caste (Klimt), and embracing sorcery over miracles (Archdeacon McDonnell). this all led to the divine bident magic that klimt gave to the man-grubs.
from here all we have to do is compare the angelic motif of the way of white man-grub magic, the serpent divine miracle, and the angels of the dreg heap. they are the same.
the way of white is, in some way, tied to the primordial serpents, and the angelic, curse-inflicting beings protecting the pilgrim abominations.
