Medieval Christians believed the pentagram to symbolise the five wounds of Christ. The pentagram was believed to protect against witches and demons (the application of the pentagram is similar to that of Occultists who use it as protection against spirits during invocation and banishing rituals) , e.g. The painting 'Christ as a Pentagram', from Valeriano Bolzani's Hieroglyphica (Basel, 1556), seen below.
「這......這......如何拆解?唉,我考證到『救星』這中文詞彙不是從Savior,Saviour而來便好了.........不知殺千刀的沙文有沒有辨法?」
「另一方面,我只好盡量去想些五角星的好處......有了,沙文不是提過,基督五傷跟辟邪劍譜一樣可以辟邪嗎?( The pentagram was believed to protect against witches and demons)我明天提出,用國旗代替八卦鏡,行不行?」
Don't know where God is but the Devil is in the details
