At the parishes I see, there’s usually luncheons, Bingo parties, and bus trips for the seniors, Lifeteen for the teenagers, and K of C for the men. Sometimes there is a “mom’s group” for moms with young children, sometimes there’s a book club. There’s really not a lot for women between age 22 and 60, but often they’ll get involved in a Bible study group, a prayer group, or a ministry like making prayer shawls or cooking casseroles for elderly parishioners.
There are also some activities that tend to happen at a diocesan level or across a bunch of parishes, like Theology on Tap or Catholic Young Adults of ___ County, that will have a get-together a couple times a month so people mostly in their 20s can meet each other and socialize.
