Now thinking is replaced by speaking. Thinking is timeless speaking is bound to time and nourished by time. The present kingdoms have no remaining form, because the redemptive future shines already into the present. Rosenzweig saw this anticipation of the eternal kingdom realized in the communities of synagogue and church, in their alternation of everyday life and day of rest, their liturgy and their festive year cycle. In this last part of his book he enquires about truth, this innermost chamber of revelation, of the name of God.
Truth has to become our truth.
This is the continuous task of synagogue and church, to prove the one truth of God, truth which is given to them only as divided earthly truth. And they do this in prayer and commandment, with which they keep the thirst for the eternal kingdom of redemption unquenched in the midst of the unredeemed kingdoms of this world. Each prays and lives according to truth as each receives and understands. The Star of Redemption does not lead us out of this world beyond reality. Rather it concludes with the stepping out into the world with the task of proving the truth in the world.
