Here's how it is seen.
chaos's real name (I cannot spell it for the life of me, but it's Yoshima or something like that.) It means Jesus. Thus, seeing why he has the aura and angelic powers.
As far as the white testiment..that deals with a saying Wilhelm stated, (or it could've been chaos who said that.) "The rider of the white horse." That would be Albedo. And Wilhelm makes a reference to that later in the game. Because if you remember correctly, chaos is talking to Wilhelm outside the hull of the Durandal. So how did he go from there inside within the matter of seconds?
Like I said, there's many conspiricies against it.
