This Jewish man goes to his rabbi with a problem.

"Rabbi," he says, "I am very upset, and I don't know what to do. My son has become a Christian."

The rabbi says: "I don't know what to to tell you. My son has also become a Christian."

"Really? Well, what did you do, rabbi?"

"I prayed to God."

"You did? And did He answer?"

"Yes, He answered."

"Well, what did He say?"

"He said he didn't know what to do either: His son also became a Christian!"
