Have you met witches (I’m sure you haven’t) or are you regurgitating Satanic Panic here?
And how do you, oh Glenda, read the hearts of witches?
I have met witches/warlocks, in fact the leader of a local coven. They were “nice” people, we got along well, and I helped my co-worker advance in our mutual work. Nonetheless, our church teaches that witchcraft and sorcery are gravely evil:
Divination and magic
2115 God can reveal the future to his prophets or to other saints. Still, a sound Christian attitude consists in putting oneself confidently into the hands of Providence for whatever concerns the future, and giving up all unhealthy curiosity about it. Improvidence, however, can constitute a lack of responsibility. (305)
2116 All forms of divination are to be rejected: recourse to Satan or demons, conjuring up the dead or other practices falsely supposed to “unveil” the future.48 Consulting horoscopes, astrology, palm reading, interpretation of omens and lots, the phenomena of clairvoyance, and recourse to mediums all conceal a desire for power over time, history, and, in the last analysis, other human beings, as well as a wish to conciliate hidden powers. They contradict the honor, respect, and loving fear that we owe to God alone.
2117 All practices of magic or sorcery, by which one attempts to tame occult powers, so as to place them at one’s service and have a supernatural power over others—even if this were for the sake of restoring their health—are gravely contrary to the virtue of religion. These practices are even more to be condemned when accompanied by the intention of harming someone, or when they have recourse to the intervention of demons. Wearing charms is also reprehensible. Spiritism often implies divination or magical practices; the Church for her part warns the faithful against it. … (Catechism of the Catholic Church)
One need not judge the heart of a person doing witchcraft, but should discern their actions and words by the above objective criteria, and work at a spiritual level against what they (sometimes unknowingly) are doing (perhaps, playing at). They also “played with” other serious sins, which eventually were their undoing. I found it necessary to eject their black candles and other paraphernalia from our mutual workplace as follows. My spiritual director, a priest, recommended I pray against the presence and power of the devil using sacramentals, such as blessed salt, holy water and holy relics. The wiccan paraphernalia were then withdrawn by their owners. One should not undertake such spiritual warfare on ones own, but with prayerful partners and spiritual direction. There is a significant kickback at the spiritual level, in temptations to sin and in “bad luck.” Satan does not wish to be opposed. Compared to me, Satan is powerful. Compared to God my Master, he is nothing.
