What is Stephen Colbert(fictional)'s religion?

Okay, I'm a The Colbert Report fan and I talk about religion a lot on my blog. So, I decided to discuss the fictional Stephen Colbert's religion. He had made statements in The Colbert Report supporting Christianity and Judaism(okay, he said it on The Daily Show).

JUDAISM:

Okay, Christians don't celebrate Channukah for religious reasons, at least most of the time. So in this clip he is Jewish.

CHRISTIANITY:

Here, according to this clip, Stephen Colbert is a Christian(Roman Catholic to be specific).

I would say he is a Seven-Day Adventist, he is Christian but he practice some Jewish(or OT) stuff most Christians don't.
