Christian belief, all things existing in Creation have a presiding angel or personification of its divine life force.

Each unit of time was attended by its own angel because units of time were considered manifestations of Divine Order. It is common in ceremonial magickal practice to appeal to the angels who represent the appropriate day and hour when the magickal work is taking place. The oils can be used to anoint altar candles if specific ones are being used for these spirits or the appropriate incense pertaining to each entity can be lighted or dropped onto the charcoal as each angel is named and summoned.
