When disciples find themselves in strange new territory, they Will spontaneously extend the pattern. It is but a small step from the notions of performing the world implied by the text and extending the pattern of Jesus Christ to that of improvising with a script.
Kevin Vanhoozer in Gary T. Meadors, Four Views on Moving Beyond the Bible to Theology. Harper Collins, 2009, 172.
Vanhoozer is rapidly convincing me that his performing the text metaphor, when mixed creatively with his disciples on the Way metaphor, captures much of what is best about talk of trajectories while (perhaps) avoiding the problems with that metaphor, and also (largely) avoiding the knee-jerk responses talk of trajectories seems to provoke.
