Here’s a closing commission and benediction for Transfiguration Sunday (the last Sunday before Lent). It comes from the Cokesbury website.
Commission and Benediction
(inspired by Mark 9:2-9 and Matthew 17:1-9)
Come down from the mountain with mountain-like faith.
Walk on God's paths as bright, shining lights.
Live in God's ways with faith, hope, and love.
Go into the world transformed and renewed!
