How old is Maria?

Every Monday, a rabbi, a priest, and a preacher gather in a coffee shop to discuss their spiritual lives. During one of these meetings, the priest challenges the others to a unique bet: he believes he can convert a bear in the woods to his religion. The others are intrigued and accept the challenge, agreeing to share their experiences at their next meeting.
The following week, they all meet in the hospital, each in varying degrees of injury. They decide to convene in the rabbi's hospital room.

He says
"Well, when I finally happened upon it, I wrestled that thing to the ground and started beating its head with a Bible.
So he lunges at me and we tumble down this hill into the river where I dunked him seven times.
Finally, he came to the faith. He'll be coming to church next Sunday."
