16 “Whoever listens to you listens to me; whoever rejects you rejects me; but whoever rejects me rejects him who sent me.”
17 The seventy-two returned with joy and said, “Lord, even the demons submit to us in your name.”
18 He replied, “I saw Satan fall like lightning from heaven. 19 I have given you authority to trample on snakes and scorpions and to overcome all the power of the enemy; nothing will harm you. 20 However, do not rejoice that the spirits submit to you, but rejoice that your names are written in heaven.”
21 At that time Jesus, full of joy through the Holy Spirit, said, “I praise you, Father, Lord of heaven and earth, because you have hidden these things from the wise and learned, and revealed them to little children. Yes, Father, for this is what you were pleased to do.
The angelic nature
Saint Makarios the Egyptian, Other seven homilies, About the arrogance of mind, 6, in Church Fathers and Writers (1992), vol. 34, p. 317
Each one of the mentioned creatures is according to own nature a body; body has the angel, the soul and even the demon. Even if these creatures are refined however in the essence of their hypostasis, despite the finesse of their nature, they have a refined body. The body in its essence is a dense element while the soul is a refined element. But this last one comprises and covers the limbs of the body. It covers with attire the eye which sees, to the ear which hears, to the nose and in one word to all the limbs of the body. By covering them with attire the soul is unified with them and from it begins everything happens in this life.
Saint John Casian, Spiritual talks, 1st part, The first talk with father Serenus, Cap. XII, 1-3, Cap. XIII, 1-2, in Church Fathers and Writers (1990), vol. 57, p. 421
`Although we say there are certain spiritual natures, like the angels, archangels and the other celestial powers and even our own soul and of course this fine air, we should not consider them completely bodiless. They have a body where they live but much more refined than our bodies are, according to the teaching of the Apostle who says: «Celestial bodies and earthly bodies».
And also : «It is born as an animal body and elevates itself to a spiritual body».
Form these it is understood clearly that there is nothing without body except for God and for this reason only He can penetrate all the spiritual and intellectual matter as He alone is all in all and everywhere so He sees and knows all the thoughts of the people, the inner feelings and the depths of the mind.
Saint Basil the Great, Homilies at Psalms, Homily at psalm XLIV, I, in Church Fathers and Writers (2011), vol. 4, p. 497
`No one of them is a child or a young or an elder but remains in the state in which it was created from the beginning and keeps its nature pure and unaltered.
