At the time when the Gospels were being written and first used, the Church was well aware of a distinction between the "the Jesus of history" and "the Christ of faith" to use the modern cliches; and that, in so far as the Gospels were used in Christian worship at all (and we shall have to ask how far, after all, that was the case), they filled a place broadly comparable to the narrative parts of the Hebrew Scriptures in the Synagogue, as the historical background against which the interpretative writings might be read (165).
Remain in some sense distinguishable from theological deductions, form the preaching of the way of salvation, and from adoration. It is only one ingredient in worship; and its very nature demands that, so far as possible, it be kept in this distinguishable condition and not overlaid by interpretation.
It is the task of the church to read these narratives of Jesus historically so as not to fall into the same pit.And--another point--its purpose accordingly was not only or even chiefly to be sued for worship. Still more, it was to equip Christians with a knowledge of their origins, for use in evangelism and apologetic. The real core of worship was the experience of the risen Christ within the Christian church through the participation in the Spirit [this sounds like Bonhoeffer -- forgive me I'm reading Joel Lawrence's book]. But [heres the important bit] Christians knew well that if they lost sight of the story behind that experience their worship would be like a house built on sand; and that if they preached salvation without the story of how it came they would be powerless as evangelists; and that if they could not explain how they came to stand where they did, they would be failing to give a reason for their hope.
