The symbol of the cross in the church points to the God who was crucified not between two candles on an altar, but between two thieves in the place of the skull, where the outcasts belong, outside the gates of the city. It does not invite thought, but a change of mind. It is a symbol which therefore leads out of the church and out of religious longing into the fellowship of the oppressed and abandoned. On the other hand, it is a symbol which calls the oppressed and godless into the church and through the church into the fellowship of the crucified God.
From: Jürgen Moltmann, The Crucified God
It is no longer a worldly throne and kingdom as it once was but a spiritual throne and kingdom.
Where are Jesus’ throne and kingdom?
They are where he himself is present, reigns, and governs with his word and sacrament, in the church, in the congregation….
We are called into this kingdom. We can find it, within the church, in the community of the faithful, when we receive the word and sacrament of the Lord Jesus Christ and submit to his authority, when we recognize the child in the manger as our Savior and Redeemer and let him bestow on us a new life grounded in love.
From: Dietrich Bonhoeffer’s Works, v 16, p 616, “Christmas Night Sermon, 25 December 1940”.
