Dear Christina:

You need to inform your family friend that she is risking her soul by involving herself with Tarot Cards, Spirit Guides, and the like. Tarot Cards are divination, a sin against the First Commandment and a grave sin.

The Catechism states:

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.

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. Recourse to so-called traditional cures does not justify either the invocation of evil powers or the exploitation of another's credulity.

If your family friend is sinning with this divination and also receiving communion then she is committing the second most serious sin possible — sacrilege against the Holy Eucharist.

Spirit Guides are demons. Have absolutely nothing to do with spirit guides. Angels are not spirit guides and neither are human spirits. In very rare instances God may allow a person in heaven or purgatory to visit a relative. This is very rare and the visitation will be to the relative directly, not through someone else like your family friend. 

As for the Anointing of the Sick, that is permitted only if a person is in danger of death. The Rite uses Holy Oil. The Lourdes water is meaningless and not part of the Rite.

Why would the devil be involved in this? The devil has no problem suggesting that you receive the Anointing of the Sick, which is a good thing, if it will draw you and/or the family friend into curiosity or belief in spirit guides. A common strategy of the devil is to do something good for a person to draw them into sin, and then later let the hammer fall of demonic attachment or worse.

Never listen to this family friend again on these matters. Warn that person to stop their dabbling in the occult divination (which is what Tarot is) and conjuring or accepting spirit guides. Her eternal soul is at risk.

God Bless,
Bro. Ignatius Mary
