Mark Zuckerberg is a true believer again.

The Facebook founder, who formerly identified as an atheist, revealed last week that religion has come back into his life in a holiday post.

He posted a short message on Facebook wishing his followers a: “Merry Christmas and Happy Hanukkah from Priscilla, Max, Beast and me!”

One of his devout fans questioned his religious views, writing in a comment, “Aren’t you an atheist?”

And Zuckerberg responded.

“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 wrote.

Zuckerberg’s wife is a practicing Buddhist, which he has taken interest in. He even said a prayer in front of the Wild Goose Pagoda — a Buddhist landmark in Xi’an, China — during a 2015 visit.

“Priscilla is Buddhist and asked me to offer a prayer from her as well. Buddhism is an amazing religion and philosophy, and I have been learning more about it over time. I hope to continue understanding the faith more deeply,” he wrote in a post that included a photo of him kneeling in front of the pagoda.
