I am always amused when people take the position: "you are actually worshipping the Devil, you don't know it, but you are doing it on accident, if you only knew what your own symbols meant, then you would understand that you are worshipping the Devil. I know YOU don't think that the symbols are about the Devil, but they are, and by using them you are actually accidentally worshipping the Devil." For one example of this ridiculous approach applied to the Mormons see:
here and here). For example the following is a great example of the pentagram (even with the point downward) used as a symbol of Christ. It is an icon of the transfiguration by Andrei Rublev in 1405, and now located in the Moscow Annunciation Cathedral (in Moscow Kremlin):
However, such evidence makes no difference to people who see the Devil everywhere, because they just see any early Christian use of the pentagram as due to those early Christians having been deceived (much in the same way that they see Mormons as having been deceived). Thus any early Christians who might have used the pentagram were worshipping the Devil too. Thus Mormons and their critics tend to talk past each other on this issue.
The problem is that people don't understand that symbolism is a language, and the real question should not be "what does a symbol mean" but should be, "what does a symbol mean to those who used it when they used it." For example, a black cat symbolized witchcraft if you happen to have lived in Salem Mass..., on the other hand, if you lived in ancient Egypt, the black cat symbolized divinity.... This sort of confusion happens because symbolism is a language, with different vocabularies and different interpretations for different people at different times. You wouldn't expect all words to have the same meaning in Spanish that they do in English, so why should they in symbolism? So to accuse an English speaker of worshipping the Devil because of a confusion between the meaning of a word between English and Spanish would be silly. But when you begin to believe that Satan is behind it all, and that it is all some big conspiracy, then you believe that black cats mean witchcraft in Ancient Egypt too, and the Egyptians who saw black cats as symbols of divinity were just worshipping the devil, and didn't know it. After all, such people often think that all Pagans were worshipping the Devil (even when they didn't believe in him), so why not the Egyptians?
But my understanding (and C.S.Lewis's understanding too) is that you can't worship the Devil on accident. Any good intentioned worship of the Devil IS worship of Christ, and any bad intentioned worship of Christ IS worship of the Devil (see CS Lewis' conclusion to the Narnia series, "The Last Battle" for his take on this idea). On this point I must agree with Lewis. Thus, Mormons are only worshipping the Devil with their pentagrams IF that is what THEY think the pentagram means... because they can't be "accidentally" worshipping the devil, it doesn't work that way. All that is good comes from Christ, and all that is evil comes from the Devil (see Moroni 7:5-19).
1. symbolism is flexible,
2. symbolism's meaning is only defined in the context of what someone, sometime thought it meant,
3. worship of God or the Devil must be intentional, some hidden meaning behind symbols can't cause you to somehow accidentally worship the Devil.
