“Many live in the illusion that the true unity of the church would be won if the great majority of Christians would agree to the same dogmatic formula. But identity of dogmatic formulas is of no importance. There must be unity in faith, that is, in unconditioned trust in the Word of God. Each one may say it and confess it as he wishes.”
Manfred Mezger, quoted in Werner Harenberg, Der Spiegel on the New Testament (London: Macmillan, 1970), 39.
