Also
-Kaworu is Jesus.
-Him taking Shinji's bomb collar is him taking the sins of man upon himself.
-He dies so that mankind can be saved.
-He is both the first angel, the son of the first angel, and the last angel, just like how Jesus is the son of god, and god incarnate, and god is both alpha and omega beginning and end.
-Gendo's glasses, and in Eva 3.33 his badass visor thing, and how they hide his eyes, is symbolic of the "the eyes are the window into a person's soul" belief, and how Gendo hides himself from the world, and in Eva 3.33, how he has given up his soul for his desires, which is why he has the visor.
