The founder of Facebook has found religion, it seems, according to a cheery holiday message he posted on the social network he created.

On Christmas Day, Zuckerberg indicated in a Facebook status that he was “celebrating Christmas.”

“Merry Christmas and Happy Hanukkah from Priscilla, Max, Beast and me,” he wrote, naming his wife, daughter and dog. Then a commenter asked him: Aren’t you an atheist?

Zuckerberg identified himself as an atheist for years, but on Facebook on Christmas he wrote back: “No. I was raised Jewish and then I went through a period where I questioned things, but now I believe religion is very important.” He didn’t answer further questions about what he does believe in.

Zuckerberg and his wife, Priscilla Chan, have publicly discussed their moral values frequently — including in a lengthy letter when their daughter was born a year ago, in which they pledged to donate 99 percent of their Facebook stock, which at about $45 billion at the time was one of the largest philanthropic commitments ever.

And they’ve already met one of the world’s most important religious figures: Pope Francis, with whom they discussed bringing communication technology to the world’s poor.
