The white portion reminds me of the Latin cross: arms of equal length. The white circle is reminiscent of Celtic crosses. The four arcs surrounding the white shape remind me of
firefighter badges. The images within the arcs have ties to both the Old and New Testament:
Upper left: the rains that caused Noah's Flood
Lower left: looks like wheat, maybe the bread of communion?
Upper right: a butterfly? Not sure what that has to do with anything, stumped me.
Lower right: grapes - water-to-wine, wine of communion
Bottom: the water from the stone, one of Moses' Miracles of Exodus. Also may be mt. Sinai. May also be the "Rock" upon which the church of Christ was built.
The octogram (8-point star) doesn't seem to have any connections to the Abrahamic religions. The radiating yellow lines probably have something to do with the light/love/grace of god. And finally, the color purple has long been a symbol of royalty. I believe this originated in Rome.
That's all I got.
EDIT: I found some thin connections between the Abrahamic religions and the octogram- the star of Lakshmi is used to mark the entrance to a secret temple in
The Sword of the Templars by Paul Christopher. Also, it's the symbol of King Solomon in
Magi, the Labyrinth of Magic, some Japanese Shonen Manga I've never heard of (not much of a surprise, I don't really pay attention to manga).
Both of these are blatantly fictional, so the connections they make are probably very... Unreliable.
