A great quote from a great theologian, Henri Nouwen:
“One of the main tasks of theology is to find words that do not divide, but unite, that do not create conflict, but unity, that do not hurt but heal.” (https://www.brainyquote.com/authors/henri_nouwen)
Nouwen was born Dutch, but spent much of his academic life in the United States. In fact, he did a stint at the Yale Divinity School as a professor of pastoral theology (1971-1981). His words say much about where theology should lead us. It should lead us to finding ways to live in harmony with one another and, of course, in harmony with God, leading the life that God has planned for us.
The 133rd psalm is in the lectionary for this week, the Second Sunday of Easter (Year B). My feeling is that a reading of this Psalm, a full immersion in this psalm, will lead us to the inescapable conclusion that unity is one of the qualities that we must seek, and to do this we must seek it in one another. And this spans the people of the whole world, not just the narrow categories that we attribute to peoples or nations.
Here is the World English Bible translation of the 133rd Psalm:
