SMI Lenten
Parish Mission

Feb. 26, 27, 28
with Mike Patin

Burros, Basins,
Bricks & Bouquets

The Symbols of Holy Week lend us to  take a look at every day living and connect them with Jesus’ final week on earth. We will reflect on these images and themes during the mission. Please join us in church at 7 pm for this parish mission. All ages are welcome and ASL interpretation will be provided. Mike Patin, our Mission Speaker, is an Internationally Renowned Speaker from Lafayette, LA. Mike uses energy, humor and stories to affirm God's goodness and presence among us while inviting others (and himself) to take the "next step" in our journey with God.
