Eight Texas churches located just a few miles apart have caught fire since New Year's Day.
The suspicious fires have put pastors and congregations across east Texas on edge.
Police say six of the seven church fires that started last month took place just nine days apart, with seven of them set intentionally.
Now authorities are investigating whether the fire that broke out at a Wills Point church on Thursday is also the result of arson. Investigators are also looking into if the fires are connected.
Some congregations in the area have installed security systems while others have enlisted church volunteers to keep watch.
Although the fires have some church members wondering if their church will be next, many are keeping the faith.
"It's heart wrenching," church secretary Nancy McDonald said. "That's your house, that's where your church family is."
"But it's just a building, keep telling yourself that," she said. "And that's evident when you go talk to the other church members. They're already set up for Sunday morning. We've got another building they can move into and they've got it all ready to go. They're amazing."
Federal officials say no one has been injured in the fires, but the cost of property losses are in the millions.
