It comes as tensions continue to rise in the U.S. after over two months of heavy Israeli bombing in Gaza, where Hamas is holding over one hundred hostages.
Reverend Peter Pettit says the service isn't for any one particular cause, and that it's not a place for slogans or politics.
"What we're hoping to do is to, first of all, provide a place where people can find a time of peace to sit and listen and sing and pray for the peace that we all desire and cherish."
Leaders from the local Jewish, Muslim, Buddhist, and Unitarian communities will be there, plus multiple Christian denominations. Pettit says that Christians should look out for other religious groups.
"We are the ones who, first of all, most need to make sure that our power and influence are doing no harm," he said. "With our power and influence, we are opening up space and opportunity for others to be present in the public square with their voices, respected, affirmed, and valued."
He says the service is open to anyone, including those who aren't affiliated with any religion. There will also be ASL interpreters.
The Prayers for Peace gathering is at St. Paul Lutheran Church in Davenport.
