The front door of St.Lugadius Church of Ireland building in Clonleigh in Lifford was forced in by vandals last week.
The gang then smashed pictures, tried to break into a safe before trying to set the building on fire.
It was the third time in in a few weeks that the church was targeted by gangs.
Now Rev John Haye has called a meeting for tomorrow night to examine how people can keep their church safe.
“Enough is enough. This was the third attack and locals on both sides of the community are disgusted by what has happened.
“I know these acts are being carried out by young people who have drink taken and are hanging around the church grounds.
“I would appeal to them or to their parents to help us stop this kind of thing happening again.
“We are meeting to examine ways of ensuring our church is not burned down in any possible future attack,” he said.
Meanwhile the Deputy Mayor of Derry, Cllr Mary Hamilton, revealed her family’s grave had been vandalised at Clonleigh Parish Church this week.
She said she was shocked to find vases had been smashed and other mementoes destroyed.
She said she sat down at the grave and simply cried.
“I was devastated and I condemn these attacks. I just came out and croied and got some flowers to put back on it.
“I would love to meet these people and ask them why they done it.
“Our family are originally from Lifford and were farmers. We probably sat down and ate with the fathers and mothers of these people.
“I would like to say to these people to treat others how they would like to be treated,” she said.
