Over the years I’ve done the Narrative Lectionary I have generally joined with colleagues in my area to do our own thing in the summers. The Working Preacher suggestion for this summer is a series on Jeremiah. Below are some of the series I’ve been a part of over the years.
The summer of 2020 our little group put together a series on Commemorations. We generally tried to have each Sunday tied to a commemoration that was for a nearby time, but that wasn’t always possible. You can find that series here: https://freedfromfreedfor.org/2020/05/26/2020-summer-series/
For the summer of 2019 we did a series on “Unsung Heroes of Scripture,” you can find that series here:
Way back in 2018 our series was on “Women of Scripture,” which can be found here: https://freedfromfreedfor.org/2018/05/17/what-were-doing-for-the-summer/
You can check out the posts from those summers to see what sorts of resources I supplied for them. You can also try clicking the “summer” tags that can be found at the bottom of this post. Please feel free to use any of these or adapt them as suits your purposes!
