In the 1980s, we had a pro-abortion politician in Maryland, Connie Morella, who was lector at St. Bartholomew’s parish in Bethesda. This went on for years and years. Cardinal Hickey (Democrat in his DNA) didn’t lift a finger. Eventually, a new pastor arrived, and he ordered her to stop serving as a lector. I don’t recall the issue of Communion coming up. This was before Cardinal Burke’s “discovery” of Canon 915. (I.e., Cardinal Burke “discovered” that Canon 915 isn’t about the divorced-and-remarried. It’s about ALL public sinners.)
I have been praying for Cardinal Burke.
