Virtues fulfill this work and, through them, God oversees the seasons and visible heavens. The powers, by tradition, are the favorite of mortals, assigned to fight evil spirits and defeat their plans. Principalities rule over the lowest hierarchy, guarding countries and charged with making announcements to mankind. They govern souls and bodies. Archangels by tradition guard great persons and, under St. Michael, they protect the Church.
Angels form the lowest rank.
They include guardian angels and stand ready to follow where God sends them.
