I've noticed an uptick in sales of Confirm not Conform Adult in the past couple of weeks. It makes me wonder if people are looking for good source material for Lenten studies. Maybe that's what people are planning, but even if they're not, I thought I'd give a few suggestions on how you could use CnC Adult as part of your parish's Lenten formation.
One of the things that makes Confirm not Conform useful is that you can pull lessons out of order and use them as stand-alone classes. With CnC Adult, you are welcome to find the lessons that match whatever theme you may want to cover during Lent and mix and match them. Here are some of the themes/subjects you might find useful:
Church History: Lessons 4, 9
Scripture: Lessons 3, 7, 8, 9 (and used throughout)
Creeds: Lessons 4, 5
Anglicanism: Lessons 9, 10, 11
Sacraments: Lessons 9, 10, 13
Book of Common Prayer: Lesson 11 (and used throughout)
The Baptismal Covenant: Lesson 13, 14
In addition, the homework for Lesson 14 and Lessons 15 and 16 are an excellent way to get people to consider how they spend their time and reflect on the direction of their lives more generally. I could imagine these being expanded out through Lent as an opening framework to get people to consider their families, their careers, their finances, and their future. The exercises in the lessons could be paired with a book, guest speakers, or some other practices to help the people in your congregation reflect on their lives and consider how God is calling them to be more mindful of how they spend their time.
The point is that you are welcome to use Confirm not Conform beyond the confines of a 16-week class. Pull out the pieces that interest you most and use them the way that best suits your congregation. Enjoy!
