In my AOG denomination we have something called “Connect Groups”. Some other local congregations may refer to them as ‘Home Fellowships’ or perhaps “Cell Groups”, or something similar.
They are small voluntary groups of usually around 25 or fewer people within a local congregation who either are of similar ages or have something else in common, like a particular interest or hobby. They meet once every couple of weeks for a meal, fellowship, prayer, and a brief Bible study led by an elder or lay leader within the church.
The purpose for the most part, especially within larger congregations, is to provide an opportunity for personal fellowship, an avenue to meet others, and strengthen the bonds of faith with their fellow parishoners under the guidance of a lay leader or some other church staff.
Do Catholic parishes do this sort of thing? Just curious.
