Welcome to Catholic Quad Cities

The Community of believers were of one heart and one mind. (Acts 4:32)


Welcome to our Vicariate homepage!


On behalf of Bishop Daniel Jenky, the Bishop of the Diocese of Peoria let me welcome you to the home page of the Rock Island Vicariate.  This area of the Diocese is comprised of 16 parishes and 20 priests.  The intention for this site is that it has the necessary links to the parishes and current events that will help us all grow in our relationship with Jesus as Savior.  Bishop Jenky in his Festival Letter for 2017 stated it this way; “Faith is always made stronger by sharing it with others. Everything we do in the Catholic Diocese of Peoria should consciously be designed to evangelize and make new disciples.”(Jenky, Fifteenth Festival Letter)

Each parish of the Vicariate works closely with other parishes to deepen our call to know and share Jesus.  As parishes working as one, we desire to fulfill the mandate of Jesus that all might be one in him as we share Christ’s love.

Please know of my prayers, as we all desire to grow in grace and holiness and celebrate our faith in Christ.  Also know that it is our joy to serve you as priests, deacons, religious and lay staff in the parishes of the Vicariate.  God bless you.
