Open Communion in the Church of the Crucified Christ

[T]he eucharist, like the meals held by Jesus with 'sinners and publicans', must also be celebrated with the unrighteous, those who have no rights and the godless from the 'highways and hedges' of society, in all their profanity, and should no longer be limited, as in religious sacrifice, to the inner circle of the devout, to those who are members of the same denomination. The Christian church can re-introduce the divisions between the religious and the profane and between those who are within and those who are without, only at the price of losing its own identity as the church of the crucified Christ.

--Jürgen Moltmann, from The Crucified God
