The belief in guardian angels is not uncommon. In the course of asking God the names of the patron saint and guardian angels for myself and others, I learned that we are all assigned to a particular archangel, who in turn has a team of angels.
There are seven archangels, one for each of the seven colors of the rainbow (attributes of God). The seven archangels are:
Archangel Uriel: Love (Red)
Archangel Michael: Strength (Orange)
Archangel Gabriel: Joy (Yellow)
Archangel Raphael: Goodness (Green)
Archangel Barakiel: Truth (Blue)
Archangel Metatron: Justice (Indigo)
Archangel Ezekiel: Creation (Violet)
We don’t just have one guardian angel. We have a lead angel (an archangel) who has a team of angels with them.
