I’m surprised that some of you see such light Mass attendance on Thanksgiving.
At my parish Thanksgiving Day always means a good turnout at Mass. We don’t have the usual 8:00am Mass, just a special one at 9:00am. This year we only had one priest but we did have five our our deacons. The choir sings. People bring baskets with their bread and wine, which are blessed after Communion.
We always use Thanksgiving readings suggested by the USCCB
While it wasn’t that way when I was a child, having a special Mass for Thanksgiving Day seemed to become a big deal in my neck of the woods in the early 1980s.
