On October 2, 1970, Apostle Benson declared in a talk given at General Conference:
Have we... "polluted the holy church of God?".... The auxiliaries of the Church are to be a help, not a hindrance, to parents and the priesthood as they strive to lead their families back to God. Do any of us wear or display the broken cross, anti-Christ sign, that is the adversary's symbol of the so-called "peace movement"?
Having received this information over the pulpit during General Conference, some Latter-day Saints assume that Benson's claim about the peace symbol is official doctrine and based on revelation. But where did he actually get such an idea? Benson was evidently parroting over the pulpit the political fear-mongering propaganda that had been published by the John Birch Society (in their official publication American Opinion) only four months before.
Titled "Peace Symbols: The Truth About Those Strange Designs," the article lambasted the peace movement by associating their symbol with a broken cross, Communism, anti-Christ, and a Satanism.
It was the upside-down broken cross. Such anti-Christian and anti-Jewish symbolism is common to Satanists...
The revolutionaries are pushing this business [of Satanism and black magic] like there's no tomorrow. And those 'peace symbols' are a part of it. They are symbols of the anti-Christ!...
[T]he actual origin of this Satanic symbol can be pinpointed....
[I]n America, as thousands of radicalized youths parade that same symbol, the heretics of the Christian have all but adopted the 'sign of the anti-Christ' as their own. And you can be absolutely certain that the Communists planned it that way.
One is left to wonder why any Latter-day Saint would find this article authoritative, since it likewise associates the inverted pentagram and hand clasp with communism and Satanism--both of which are symbols that have been used by the Church. Inverted pentagrams were depicted on the Nauvoo temple (and other buildings). The hand clasp is found on the Salt Lake temple (and other buildings) and is a central part to the temple endowment ritual.
Says the same article quoted above:
Another esoteric symbol of the international socialist movement is the "joined" or "clasped" hands--the ancient sign of the god Fides. Mackey's Symbolism says this design has been used historically to denote fidelity. It is now used by the Freemasons, the A.F.L.-C.I.O., and is frequently reproduced in the Communist Daily World to indicate union between Comrades. The insignia is the official symbol of the Communist-controlled Student "Nonviolent" Coordinating Committee, and serves as the logo for the Trotskyite Communists' Workers World....
Bernard Koerner cites the inverted cross as the symbol of "Drudenfuss," or Druid's foot. Standard German dictionaries describe this as a five-pointed star with one point up and two down. That star-shaped figure, which corresponds to the forked-shape runic figure [previously associated with the peace symbol in the article], is known in ancient symbolism as a pentalpha. In his Symbolism Of the Three Degrees, Oliver Day Street comments that "The Pentalpha with one of its points elevated, was a symbol of the pure and the virtuous and a harbinger of good, but with two of its points elevated it became the accursed Goat of Mendes which typifies Satan and foreboded evil and misfortune." One point (or finger) up, symbolized the monogram of Christ, while the inverse of the Pentalpha, or two points (two spread fingers [implying a condemnation of the Peace Sign typically made with the hand]) up, was the sign of Satan.
