Church Wardens

The primary role of the warden is to serve as the lay partner of the rector or priest-in-charge in articulating the mission and vision of the parish, managing its day-to-day operations, identifying and nurturing leaders, and empowering members of the congregation to live out the Gospel in their daily lives.
