Daily Luther: We are Pupils of the Prophets and Apostles
All theologians since the days of the Apostles, says Luther, must confine themselves in their teaching to the teaching of the Apostles: “We are catechumens and pupils of the Prophets. Let us simply repeat and preach what we have heard and learned from the Prophets and Apostles” (St. L. III:1890). Luther enforces the demand that the theologians simply “repeat the words of the Apostles after them” with the solemn warning: “Neither ought any doctrine be taught or heard in the Church but the pure Word of God, that is to say, the Holy Scriptures; otherwise accursed be both the teachers and hearers together with their doctrine.”
The same truth is expressed in the well-known axiom: Quod non est biblicum, non est theologicum. [That which is not Biblical, is not theological].
