The Rev. Tony McAfee stood on stage in front of the congregation and paid Martin for the 10 pizzas the church in Rocky Top, Tenn. had ordered. He then explained that he doesn't think a lot of churches tip as well as they should and challenged everyone gathered to help give Martin a good tip in the spirit of Thanksgiving.
"We've been doing this thing about being thankful and how good God is," he said in a video of the event posted on Facebook, "and we believe in being generous."
Martin wiped tears from her eyes as she watched dozens of congregants rise from their chairs and approach the stage to contribute.
"We just want you to know that we appreciate you," McAfee said as he handed her the money.
Martin, a single mother of three young children, depends on her job at Domino's to make ends meet for her family, she told WATE, the ABC affiliate in Knoxville, Tenn. Usually her tips add up to $10, so this one was overwhelming.
"I was just thinking how I could finally get a place for my kids because I recently lost my apartment," Martin said, "and I was thinking how I could give my kids a good Christmas."
As for McAfee, he said he got the idea for the good deed out of a desire to live out his faith.
"One of the greatest ways to illustrate our faith is action," he said. "Faith without works is dead."
This isn't the first time a church has come together to surprise a pizza delivery driver with a big tip. Just last month a woman in Ohio received a tip of $1,046 after the church took up a collection for her.
