Yes, Advent = coming, in multivalent ways.
Nah, Advent should not be thought of in terms of "coming". A soft and gentle word which fails to do justice to what happens when Jesus enters our sphere.
Here is an arguably better word for understanding Advent: disruption.
I understand that "disruption" is a bit of vogue word these days, e.g. in commerce, if one wants to make money, one must "disrupt" the market with a new product. Trump and Brexit are disruptions to the "usual way of doing business."
Yesterday, preaching on the Advent 1 lectionary readings (Isaiah 2:1-5; Romans 13:11-14; Matthew 24:36-44), I was drawn to the word "disruption." Jesus did not just come into the world, he disrupted it. The suddenness of the Second Coming will be a disruption.
Perhaps one question for the church to ponder this Advent is whether the Christ who comes and comes again in the church means the church is itself a disruption in the world?
Some would say we are blandly quiescent, passive without any aggression ...
