I am not quite sure of Ridderbos’ sacramental theology, yet in his commentary on John he remarks that the early church viewed John 9 as highly sacramental. He writes that the narrative of the blind man in the Pool of Siloam played an important role in the early church’s practice of baptism. To be clear, Ridderbos is a bit skeptical about its liturgical use, but affirms the role this account played in developing early church baptismal and liturgical practices.
