Posted on June 27, 2021. An acquaintance once told Eunice Shriver, a member of the Kennedy clan, that he wanted to write a book about the faith of her assassinated brother, John, the first Catholic president of the United States. “It would be a terribly short volume,” she quipped.* Joe Biden, on the contrary, would yield more to talk about. He is not merely a Catholic who goes to Mass and receives communion; he frequently speaks about the importance of religion in his life. At certain points, he even considered the possibility of becoming a priest. Could the second Catholic president of the United States be rightly prohibited from receiving communion, the most complete act of union with Christ?
