A call to action but what action? Are lay persons going to proselyte, maybe stand on street corners preaching the “message” or go knocking on doors?
Jesus gave his disciples a message to preach, gave them training in the field, organized the work and then had the preachers report on their experiences so they could be corrected.
I wonder what precisely is being asked of the
laity.
Don't know if you were being serious or facetious ... but several Parishes I have been involved with have lay groups whose mission is explicitly to go throughout the parish boundaries, knocking on doors and talking to folks about Jesus Christ.
The one comment I see repeatedly on many threads is that posters are often invited to attend someone's worship service and they wonder why catholics never invite them to attend their church. This same comment is often made by guests of Marcus Grodi on The Journey Home. That might be a good starting point. Invite someone to join you for church. Let God take care of the rest.
