She was the woman who led him to God, Blackwelder said Friday.
And with that firm religious footing, Blackwelder said it would be preposterous to stop praying before meals at Port Wentworth's Ed Young Senior Citizens Center near Savannah because of a federal guideline.
"She would say pray anyway," Blackwelder said of his grandmother. "She'd say don't listen."
But Senior Citizens Inc. officials said Friday the meals they are contracted by the city to provide to Ed Young visitors are mostly covered with federal money, which ushers in the burden of separating church and state.
On Thursday, the usual open prayer before meals at the center was traded for a moment of silence.
The dilemma is being hashed out by the Port Wentworth city attorney, said Mayor Glenn "Pig" Jones.
Tim Rutherford, Senior Citizens Inc. vice president, said some of his staff recently visited the center and noticed people praying shortly before lunch was served. Rutherford said his company provides meals like baked chicken, steak tips and rice and salads at a cost of about $6 a plate. Seniors taking the meals pay 55 cents, and federal money foots the rest of the bill, Rutherford said.
"We can't scoff at their rules," he said of federal authorities. "It's a part of the operational guidelines."
Rutherford said the moment of silence was introduced to protect that funding. He said although the change may have been misinterpreted, perhaps his company could have done a better job selling it.
"It's interpreted that we're telling people that they can't pray, but we aren't saying that," he said. "We're asking them to pray to themselves. Have that moment of silence."
Jones said he was outraged by the change and has promised to find a solution.
"It was one of the hardest things I ever did as mayor is to look those people in the eyes and ask them to be patient with me and honor their God in a moment of silence until I can have a resolution to this," Jones said. "For me to look at their eyes and tell them they can't thank God for their food, it's unheard of - I can't take it."
Jones said he flirted with the idea of ending a contract the city has with Senior Citizens Inc.
"Like one lady said, 'You can stop me from speaking, but you can't stop me from praying what's in my heart,'" he said. "But the best answer right now is that we're trying to get the best information possible and legal council is looking at what would happen if we continued to pray."
Blackwelder said the center's already fragile visitors have been rattled.
"This is, in my view, an unnecessary intrusion into the private lives of individuals. It's a bad place to draw a line in the sand."
