When you leave, you need to go somewhere. Make sure the room is prepared ahead of time. The faith sharing after dismissal is not catechesis. It is an extension of the liturgy. So, if possible, you want to go to a room other than the catechetical space. If that’s not possible, try to make the catechetical space look more like a prayer room and less like a classroom. You might want to have a candle, a cross, some flowers, and possibly a stand for the lectionary.
Have the chairs arranged in a circle, and place a Bible on each chair.
Try maintain an attitude of prayer as you gather. There will be time for socializing later. A simple way to keep the prayerful sense of the liturgy is to recite the refrain of the responsorial psalm from Mass and have the catechumens recite it back. If you are at all musical, by all means, sing it.
Next have everyone sit in the circle. Begin the faith sharing with a statement like this:
Today we heard readings from ______, _______, and ______. Tell us something you remember from the Gospel reading.
What do you see? Encourage everyone to share something they remembered. After everyone has spoken, ask them to go deeper into the reading. Have them open their Bibles to the passage. Ask them each to name something they see in the reading. Keep going deeper, and keep focused on what they see. Characters, scenery, actions, crowds. Ask them to describe in as much details as they can.
What do you hear? Now go around again, asking everyone what they hear in the reading. Background sounds, quietness, wind, people talking. Pay particular attention to questions they hear spoken. Ask them if they heard anything new or surprising.
Ask everyone to reflect in silence for a minute on why they think these readings matter. After some silence, ask the group questions about what the readings mean. If your parish uses a question of the week, focus on that. Or ask how, having seen and heard what they have, their lives might be different in the coming week. Ask if they have discovered anything new about themselves, about God, or about the church. Ask what questions they are struggling with.
Summarize what you heard from the group and close with a prayer of your own or the Lord’s Prayer.
