Soul King = God Juha Bach = Jesus Ichigo = Holy Spirit Aizen = A great fallen angel/archangel(aka Lucifer) Shinigami = Angels Hollows = Demons Humans = All Children of God Quincies = Children of God "saved" by Jesus(aka Christians) Fullbringers = Children of God who are "afflicted"

Also, the fact that Juha and the quincies are villains is Kubo's way of metaphorically describing how corrupt he feels Christianity is. Ichigo also being a mixture of everything at the same time as the Holy Spirit also describes and hints to what Kubo's personal beliefs are which may mean he's probably agnostic or something.
