Scot McKnight quotes Bonhoeffer on a delicate matter in Protestant/Evangelical contexts. Here it is.
For Protestant congregations there are certain prejudices that make it more difficult for the congregation to have a proper relationship to theology.
The pietistic: Theology is a matter of the head; what matters is the heart. Thus theology divides, while the piety of the heart unites.
The orthodox: All preaching is instruction, theology, true theology = true faith, the sum total of true propositions.
The academic: Theology is rigorous scholarship, study, university, not for the laity.
The evangelization [volksmissionarisch] circles: People are not mature enough for theological distinctions—first mission, then theology.
The ecclesiastical political: Theology disrupts the political unity of the church. The sectarian. A particular theology is the whole truth of the gospel.
