This story goes back to my days in grade school on the US east coast, in the late 1960s. I was attending a public school which was, literally, across the street from a Catholic school. Through some agreement between the school district and the Catholic school, students – or I should say, the parents of the students from the public school that wanted their children to have religious instruction – could sign them up to be taught the Bible and be prepared for their first communion.
As a group, we would be led over to the Catholic school at 2.30 on Wednesday afternoons for a one-hour session. The regular Catholic students left early that day, so we never mingled with them, and we were able to use their empty classrooms. There were about 60 of us from two or three grade levels.
