“The Gospel is not content to be one opinion among others of the lie but claims to be the truth, the truth that by its very nature is exclusive of every area. The church is not just an arbitrary association of people who wish to worship together but something instituted by the Lord, the pillar and ground of the truth. The world would gladly banish Christianity and the church from its turf and force it to a private inner chamber. We could give the world no greater satisfaction that to withdraw into solitude and leave the world peacefully to its own devices. But the catholicity of Christianity and the church both forbid us to grant this wish.”
Herman Bavinck, “The Catholicity of Christianity and the Church,” 248.
