Sounds like the new age stuff I used to practice in my years away from the Church. During that time, I even attended a day-long event with Doreen Virtue, the woman who assigned those numbers their meaning. While I don’t doubt her belief in what she teaches, being in her presence and hearing her do “live readings” about the angels in the room – even when I absolutely believed in this stuff – convinced me this was mostly made up.
Anyway, this number thing is a sort of numerology – that numbers are inherently endowed with spiritual meaning. The Church is absolutely against this.
Here is what is written in the Catechism of the Catholic Church:
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.
The part I made bold is the part that relates to what you’re talking about with numbers. Assigning a particular spiritual meaning to each number is a way of trying to control, as it were, the action of God’s angels.
Stay away from this. Not only is it dangerous for the soul, the number meanings Virtue invented are juvenile. And from experience, I can tell you that if you start looking to numbers for messages from God, you start to get really confusing messages. We should look to His Word, His Church, and prayer to hear God’s voice.
