We are in the 2nd session of book 2, which is on the Sacraments. My group continued to meet between the sessions using the Prayer Time Cycle A booklet (also from Renew - we had used Share the Word from Disciples in Mission, then Exploring Sunday Readings from 23rd Publications). I had a copy of the Compendium and the US Catechism for Adults, but the DRE made several copies of the Catechism available for anyone who who didn’t have one. Like several others have noted, it’s only as good as the facilitator. The questions and actions are not study, but sharing our experiences of faith - what does this mean to me and how can I apply it to my life? The response to Why Catholic at my parish has been generally good, and it’s certainly a place to start. A lot of people haven’t had any religious education as adults beyond the Sunday homily. For those who want “more meat”, I suggest volunteering on the adult formation or evangelization committee at your parish. The small group experience doesn’t appeal to everyone, and maybe there are other materials or additional avenues your parish can explore.
