I have wondered about Alex Trebek’s faith for a while.

My curiosity was piqued last May when the longtime “Jeopardy!” host — battling stage 4 pancreatic cancer — cited prayer as a factor in his “mind-boggling” recovery. He later revealed a setback that required him to undergo more chemotherapy.

In advance of ABC’s special prime-time series "Jeopardy! The Greatest of All Time," the 79-year-old Trebek sat down for an interview with Michael Strahan that aired Jan. 2. Yes, the subject of prayer came up. More on that in a moment.

But first, in case you weren’t among the 13.5 million viewers Tuesday night, this is how the competition turned out: Ken Jennings prevailed over fellow quiz show legends James Holzhauer and Brad Rutter and claimed the $1 million prize. The Bible even made a cameo in one of the Final Jeopardy clues.

Back to Trebek: As noted by Newsweek, he talked with Strahan about matters of faith and morality:

"I believe in a higher power....he or she is busy enough looking after more serious problems in the world. But I don't minimize the power of prayer," he said.

"Most of us have an open-ended life. It's no longer an open-ended life, it's a close-ended life," he said, given the poor survival rate for pancreatic cancer.

"I'm not sure I always have this positive frame of mind." He later admitted, "My self-deprecating humor is worth its weight in gold."

So, does Trebek have a specific religious affiliation?

This much is known, as I’ve pointed out before: He grew up in a Catholic household.
