Fink ,I remember a publication called "The plain Truth" that was given out free at a newsagents around the 70`s and that spoke about Armageddon and was well illustrated .Actually it was a far superior in quality compared to the WT & Awake mags.
The Adventists also believed in Armageddon in their publications and "World Tomorrow" also preached about the big "A" though I don`t think they put a date to it.
Just saying.
I`m sorry to hear stan that your wife still shuns her son ,just shows the power of indoctrination , so tragic and evil.
