At a recent worship meeting in my parish, we talked about scripture readings during worship, and whether or not the lector and/or pastor should conclude with something (like "the word of God for the people of God") or not and whether the congregation should respond together with something (like "thanks be to God") or not. Right now, this is not done consistently in our congregation.
Do you use responses to scripture in your congregation?
If so, what do you use?
Either way, do you have some theological/liturgical grounding for your decision?
