A king who stammers on his speech reminds me of how Barth said that even at our best, our theological speech is still a stammering about our King. Our theological speech is, in some sense, always improper.
“The whole historical difficulty occasioned by the Easter story itself has its foundation in the fact that in it the New Testament witness touches the point at which as witness, i.e., as human language about and concerning Christ, it comes up against its true object, against the point where everything else depends upon this object, which in itself contains the Word of revelation. Little wonder human language begins to stammer at this point even in the New Testament.” (I/2, 115)
“Even in common prayer it not only can but must and will be decisively an inward speaking, which in its inadequacy as human speaking to this Other, and in consciousness of this inadequacy, will be simply a sighing and stammering, both in its beginning and in its end. But in this respect we must not try to think too spiritually or ethereally. It is already speaking even when it is only sighing and stammering.” (III/4, 89)
