Indeed there are.
And the notion to begin with families and then with churches is also spot on.
However, there is a way to combine these two, and I’ve seen (maybe) a shift in how the suggestion I’m going to make has been “processed” within the churches.
Suggestion: begin with men-only prayer meetings held weekly. It must be men only. No women. they can (and usually do) organize their own women-only gatherings for prayer, often with no leadership from church leaders to do so.
In my first pastorate (44 years ago), I changed the Wednesday night prayer meeting to men only. It got a huge push back from many of the women, even though I assured them that they could come to the church house on Wednesday evenings and pray up a storm. But the men would meet only with other men for the same activity.
In my last pastorate (ended after 16 years in 2020 because of health-related retirement) I also set Wednesday night for a men-only meeting for prayer. No push back from the women at all (!). They even thanked me for doing that (!!).
Maybe it’s an irrelevant report I’m making. Or, maybe some women in our churches have at least a dim sense that it’s a good thing for their husbands, fathers, brothers to be in a male-only setting for something expressly spiritual.
A final observation: over the years of this male-only prayer meetings, it came to pass that conversation - serious conversation about a whole range of topics compelling to men - occupied about the same amount of time as the praying. I cannot see what happened to our prayers in the heavenly courts. I did see how the relationships among the men evolved over months and years. It was a very good thing to watch.
