One of the messages my church sent me when I was an adolescent was: Don’t date Catholic girls; you never know where it might lead. When a cousin of mine not only dated but married a Roman Catholic, the aunts had apoplexy. Church practice in those days made “mixed marriage” extremely difficult. A wedding involving a Protestant minister and a Roman Catholic priest was unheard of. The first time I was invited to be part of a wedding in a Catholic church (by an uncomfortable priest who was under unrelenting pressure from the Presbyterian bride) I was told to sit in a pew for the ceremony. After it concluded, I was invited to stand up and offer a prayer.
