It is our duty to venerate the angels: they, glorifying the Creator, reveal His charity and goodwill towards men.
St. John Chrysostome.
After the Trinity come the invisible shining Angels. They move freely around the great throne - quick minds, flames and divine spirits - and faithfully serve the high commands of God. They are one in spirit and alike among themselves: one essence, one mind, one love - around the mighty King God.
St. Gregory the Theologian.
Angels, being servants of love and peace, rejoice in our repentance and attainment of virtues, try to fill us with spiritual contemplation and aid us in the doing of good.
St. Theodore of Ephesus.
