The unity embodied in this psalm is idealistic, imaginative, and radical, embodying fluidity. It disrupts the exclusivist notion of nationalism common in its contemporary literature and embraces unity, which is symbolized as inherently good and pleasant.
Jesus, against our expectations, comes to bring division in places where unity formerly existed. He calls us to be attentive to the way the winds of our age are blowing.
As the people of Pentecost, our political vocation is to manifest the reality of God’s worldwide kingdom, to be a place where the enmity between peoples is overcome and the many tongues of humanity freely unite in the worship of their Creator. Amidst the Babelic projects of the ages, the Church proclaims by its existence that the kingdom belongs to God, that there is no other true ruler over all the nations.
The stark repetition of the admonition to being of one mind in the first and last phrases is particularly arresting, and particularly challenging for us today. After all, for contemporary liberalism, being of one mind is no virtue, and the same could be said for most contemporary Christians. We no longer think of pluralism as simply a pragmatic political strategy for negotiating irresolvable difference, but as a good in itself. It is difference, we say, that makes us strong, tolerance and indeed embrace of otherness.
