Occult symbols and their meaning

From Stanley Monteith's Radio Liberty site:

Occult symbols are fast replacing Christian symbols in our culture. Therefore, we encourage you to use this list to warn others, especially Christian children who intentionally wear and display them because they are popular.

Keep in mind that some of these symbols have double meanings. For example, the pentagram has been used to transmit occult power in all kinds of rituals for centuries, but to Christians the same shape may simply represent a star -- a special part of God's creation. The image of a fish may mean a sign of the zodiac (astrology) to some, but to Christians it has meant following Jesus and sharing the message of His love. We will continue to delight in the cross, while recognizing that others use the same image to represent their dark forces.

Please don't pass judgment on those who happen to wear these symbols. Instead, let us seek God’s will and discernment so that we might all honor Him with our lives. Remember, "each of us shall give account of himself to God. Therefore let us not judge one another anymore, but rather resolve this, not to put a stumbling block. . . in our brother's way." (Romans 14:12-13)
