Post High School & Young(ish) Adult Sunday School At First Presbyterian you will feel welcome the moment you enter. Our members are loving and friendly but not smothering. Please join us for worship at First Presbyterian Church in Green Cove Springs, Florida. Just one block from the beautiful St. Johns River. Our historic building, built almost 125 years ago is a beautiful structure created by out of work ship builders when Green Cove Springs was at the peak of its popularity.
