Who else thinks chaos is the Ethereal version Jesus? Since Xenosaga contains elements of Gnosticism, it would make since that the physical Jesus was crucified and the ethereal Jesus (chaos/Yeshua) lived. I think this was the intention of the creators, but it was never said (just that chaos had the power of Anima within him.)
shareCorrect. chaos is the ethereal version of Jesus.
shareRemember, T-elos calls Mary the "Partner of the Messiah," and since Mary is the Animus, her partner would clearly be the Anima- chaos. So, to reiterate, you would be correct that chaos is Jesus.

chaos is space Jesus. Wicked.

You can probably also conclude that Wilhelm is the Demiurge, since he practically controlled everything in the Universe.
