The subject of the class at Baylor University was contemporary movements in American religious life. On this particular day, the subject under discussion -- with the help of a guest speaker -- was debates about the meaning of the hot-button word "cult."

I was taking the class as part of my master's degree studies during the late 1970s in Baylor's unique church-state studies program, an interdisciplinary program build on studies in history, theology, political science and law. This particular class was important, since legal disputes about new religious movements have helped define the boundaries of religious tolerance in our culture.

To paraphrase one of my professors: Lots of people with whom you would not necessarily want to have dinner have helped defend your religious freedom. True tolerance is almost always tense.

The speaker in our class that day was a soft-spoken leader in a ground that would become infamous more than a decade later -- the Branch Davidians. His name was Perry Jones and it would be another five years or so until a young guitar player and Bible-study savant named Vernon Howell would arrive at the group's 77-acre Mount Carmel headquarters. Howell, of course, would change his name to David Koresh. Jones' daughter Rachel married Koresh, who would eventually become a polygamist.

The main thing I remember about listening to Jones that day, and talking to him after class, was his consistent emphasis on pacifism and biblical prophecies about the End Times -- remaining doctrinal ties back to Seventh-day Adventism, the movement from which the Davidians split decades earlier.

Why share this information? Well, this was the rather personal frame around the contents of my On Religion column this past week and the "Crossroads" podcast that followed. (Click here to tune that in.)

Both focused on religious issues -- in journalism and public life -- addressed in the six-part Paramount Network miniseries called "Waco," which will run through the end of this month.

It was, to say the least, rather haunting to see Perry Jones fatally wounded in the dramatic recreation of the first moments of the two-hour gunfight on Feb. 28, 1993 that opened the 51-day siege outside Waco by an army of federal agents. The hellish fire that ended it all -- its cause remains the subject of fierce debates -- claimed the lives of 76 men, women and children.

Were the Branch Davidians truly a "cult"?
