We are a congregation committed to glorifying God in our
Our teaching focuses on the Bible, proclaiming, explaining, and applying God’s word for salvation, faith, and life. We gather for worship as a fellowship on Sunday but we also believe worship embraces all of life and that what we hear in
We uphold the Westminster Confession of Faith and Catechisms as a faithful summary of what the Bible teaches. We believe that humanity has rejected God and plunged itself into rebellion against Him. But God in his love for us has given us his Son, Jesus Christ, and through trusting him we find both forgiveness and freedom.
