The fact that it is in faith that the truth is presupposed to be the known measure of all things means that the truth is in no sense assumed to be to hand. The truth comes, i.e., in the faith in which we begin to know, and cease, and begin again. The results of earlier dogmatic work, and indeed our own results, are basically no more than signs of its coming. They are simply results of human effort. As such they are a help to, but also the object of, fresh human effort. Dogmatics is possible only as theologia crucis, in the act of obedience which is certain in faith, but which for this very reason is humble, always being thrown back to the beginning and having to make a fresh start. It is not possible as an effortless triumph or an intermittent labor. It always takes place on the narrow way which leads from the enacted revelation to the promised revelation. (CD I/2, p. 14)
