Israel in Christian Theology

Who can name the author of this quote?

The Christian church has off and on, sufficiently or insufficiently been aware of that [the church’s continuity with Israel]. Sometimes she has regularly related the New Testament to the Old, but at other times (unfortunately, more often) she has read the New separate from the Old. In some respects she is intensely concerned with the Old Testament; think of the important place Israel has in her instruction or the Psalms in her liturgy. In other respects she seems to forget Israel almost completely and not need her at all. The latter is especially the case in the creedal statements and systematic theology handbooks. An example is the structure of the Apostles’ Creed: the confession jumps directly from Creator to Christ. This happens especially with an unhistorically veritical trinitarian mode of thinking; beginning with the Father who is the creator, one continues with the Son who is the redeemer. In the study of the faith this can never be consistently maintained, for in between creation and redemption one must assume the fact of sin. But usually one proceeds then directly from the doctrine of sin to Christology. There is hardly room and interest for God’s history with Israel. The impression is given that after a long period of divine inactivity, Jesus drops out of heaven.
