Did the religious overtones of A Prayer for Owen Meany seem to smack you over the head as you read it? Well, they ought to, considering that religion plays such a strong part in the novel. No sooner do you read the first paragraph than you find out that John, our narrator, is a Christian because of Owen Meany. We spend the rest of the novel figuring out why that's the case. Owen himself is presented as a Christ-like figure (for more, see the "Symbols" section). Much of the novel centers on the struggle to find faith and to maintain it in light of trying circumstances. We get to know a lot about how religious belief is not fixed; it goes through all kinds of ups and downs. Some characters have it and will always have it; others don't have it at all. Some, like John, gain a sense of religious faith only after witnessing something truly miraculous.
Owen Meany is a Christ-like figure because he inherently possesses characteristics that make him seem like Christ.
Owen Meany behaves in a Christ-like way because he wants to be seen as such.
