Teaching is eschatological. The gospel imperative constrains us to live out of the gift which we were already given. The gospel is an event. Doctrine is interpretation. And the Scriptures relate no event in isolation from interpretation.
Doctrinal purity is the product of the vital relation of dogma to event.
As the fruit is to the vine, so is dogma to event. In isolation from the event, dogma can do nothing. The redemptive historical doctrine belongs to the church only as the redemptive event belongs to the church, and the redemptive event belongs to the church only as the church belongs to the Redeemer and the Redeemer to the church. 2 Doctrinal purity may never be compromised for the sake of outward unity. The gospel event creates a unity in doctrine because it is a unity in Christ and in His death and resurrection.
