In a worship series focused on justice, the best concrete actions are, of course, acts of justice. These stations are not meant to be the end of the response. They are meant to reinforce worship and serve as additional motivation for working toward justice beyond the walls of the church building.
Ascension, Pentecost, and Trinity Sundays deal with heady theological stories and themes, so it’s especially important to reinforce them in concrete ways that interact with our senses. We learn best when not just our brains but all of our human capacities are engaged.
