The virtues are ranked fifth in the heavenly host out of the nine choirs of angels. They are members of the second triad with dominations and powers. As a member of this triad, they take part in the duties given to the three choirs, namely the ordering of the universe. The virtues specifically preside over the elements of the world and the process of celestial life. Thus all heavenly bodies-from the stars and planets to the galaxies themselves-are kept in their divinely appointed routes and progress. On earth the angels maintain a watch over nature, marking and guiding every facet of natural life: rain, sow, wind, etc. It has also be speculated that Virtues are in charge of miracles.
As if these duties were not enough, the angels also assist humanity by stowing grace and valor within the mortal heart. They encourage humans to turn always to the good and help enhance the person's will to endure hardship and suffering and to have the personal strength to turn ever toward God. As the angels in charge of miracles, they receive their orders from the powers, but they are also closely interlaced with the saints.
