Dear Jan:

I am still confused as to why you are reticent to speak to priest about this. It seems to me that is like being sick and not discussing the illness with doctor. The House Blessing, however, can be done on your own, or we can lead it over the phone. Many priests may not do that more extensive blessing, but will do a regular blessing, and thus the Blessing Ritual may have to be done by you or with us leading it anyway.

You can exclude anything you want from the House Blessing ritual, but I do not advise it. Even you move shortly, the medals should be part of the blessing anyway.  The medals are suppose to be placed somewhere, if possible, where they will not be disturbed (e.g. under the carpet, inside the wall if possible, on top of a door frame, etc.). If you have a yard, medals are buried in the yard according to the Ritual. New residents will never know that one. Even if new residents remove the medals they find in the house, the medals still serve to provide a blessing not only to the house, but to the new residents. Besides, it is presumptuous to expect the new residents to remove the medals. You do not know they will do that. And, as I mentioned, the medals will serve to bless them, even if they remove them.

The second part of your question that I forgot to answer was:

Pendulum was used in the house. Is it certain that the spirit communicated with was a demon or the devil? Or is it possible that the spirit was a guardian angel, which is who the person thought they were communicating with.? Please advise what to do that would be best for this situation.

Angels of God do not communicate through occult devices. If there was an actual spirit communication using a pendulum, which is a tool for divination, then that spirit was a demon.

The person or persons using the pendulum needs to renounce this sin of occult and divination, which is a sin against the 1st Commandment, seek Confession, and never do it again. Involving oneself in such things can open doors that ought not be opened.

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. 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.

God Bless,
