About creation

So, for the good and too good God was not satisfied with the contemplation of his own, but the crowd goodness deigned to do anything to receive His favor and partake of his goodness, bring non-existence to existence and creates the universe both the invisible and the visible, and man, which is composed of visible and invisible elements, while thinking, creates; and the thought is work being carried out by the Word and the Spirit perfecting it.

About angels

He is the maker and creator of angels; He brought from non-existence to existence and has built after His own image, nature intangible, a kind of spirit and fire immaterial, as says divine David: “He who makes His angels spirits, and his servants a flaming fire “. These words show that they are lightweight, flame, hot, crossed, hurrying to the longing for God and His service, head to the top and free from any material thought.
So the angel is a spiritual being, always moving, free asset; serves God and received the nature of immortality in grace. But what is the nature and definition of his being, only the Creator knows. They say it’s intangible and immaterial relative to us because everything is put in comparison with God, only incomparably it is crass and material. Only the Godhead is really immaterial and intangible.

So the angel has a rational nature, spiritual, free, and changing the way we think or you, for everything that is created is changeable. Only that which is uncreated is unchangeable. Everything is rational and free. So, for that angel has a rational and spiritual nature, it is free; and because it is created and changed, it has the faculty to remain and progress for the better or worse heading to (if nn fallen angels).
Angel is incapable of repentance, because it is intangible. The man, however, because of the weakness of the body is part of repentance. Angel is immortal not by nature but by grace, because everything has a beginning has an end according to his nature. Only God is eternal but rather is above eternity. For at that time did not in time, but over time.
Angels are spiritual side lights, which have their primary illumination of light without beginning. No need language and hearing, but some others transmit their own thoughts and judgments without uttering a word.
All the angels were built by the Word and the Holy Spirit were perfect consecration, participating in light and grace as far as worthiness and their rank.
Angels are circumcised because when you are in heaven and not on earth they are sent by God on earth remain in heaven. Are not limited to walls, doors, locks and seals, as are unlimited. I say unlimited. However they do not appear as worthy to whom the offering God will show them to you, but in some form, so as to be able to see which ones are shown. Unlimited but by nature and in the proper sense of the word, it is only the Uncreated, for all creation is limited by God, who built it.
They have their being outsiders holiness of the Holy. They have by divine grace, the gift of prophecy. No need of marriage, because there are mortal. As spirits, they are spiritual places. There are circumcised in the way of tangible nature has no bodily form, nor have three dimensions, but spiritually present and active where they would command; however they can not be and work simultaneously in two special places.
We do not know if their being is the same or differs from some others. Only God, whom he did know, he who knows all. Are distinct from one another by light and by rank, be they rank according to the degree of light or enlightenment that participate are suitable rank; they illuminate each rank or superiority according to the flesh. But it is obvious that those who are above the lowest share enlightenment and knowledge.
Angels are strong and ready to fulfill the divine will. By the swiftness of the flesh are everywhere would soon consent divine commandments. They keep parts of the world. They are forward-stătătorii of nations and places, as were ordained by the Creator. They lead us and help us in our stuff. Surely, according to the divine will and commandment they are superior to us and are always around God. They leans heavily toward evil, but are not unapt into. Now, however, they came unapt into, not because of their nature, but by grace and perseverance in only better.
I see God as much as is possible and this is their food.
They’re bigger than us, because they are intangible and free from any bodily passion; however not complacent, for only Godhead is impassive. Take shape that would command a Lord God and thus shown to people and reveal the secrets of God. Dwell in heaven and have only one thing to do: to praise God and serve His divine will.
Most Holy and most holy and great theologian Dionysius says that all theology, that Scripture indicates nine celestial beings. These divine teacher divides them into three companies of three.

He says that the first band is that God is always near and, according to Tradition, closely united and directly with God. This is fog Seraphim with six wings, Cherubim and Thrones many eyes with the holy.
The second band is fog reign, the power and dominion.
The third and final band, the beginners, Archangels and Angels.
Some say that the angels were made before any creature, as Gregory the Theologian says: “In the beginning God thinks angelic and heavenly powers and thought his work was done.” Others say that were made after they created the first heaven. All, however, I confess that were made before the fabrication of man. But I am of the opinion of Gregory the Theologian. For had to be built first and then the spiritual being sensitive and behind, of the two, the man himself. But all that said angels are creators of some beings, are they mouth their father, the devil. For angels are creatures, not creators. E
veryone Maker, Keeper and Caregiver is God, the only Uncreated, the praised and honored the Father and Son and Holy Spirit.

The devil and demons

Of these angelic powers, before Primate troop Land which God has entrusted to keeping the earth, has been hurt by nature, but it was good, it was done well and not have it from the Creator the slightest trace of malice ; however he not suffered enlightenment and honor the Creator and has given it, but by the will of free, was directed from its natural state to a state against its nature and was up against
God who made him, trying to resist him. He is the first who was well away and fell into evil. Evil is nothing but the absence of good, just as darkness is the absence of light. For the good is spiritual light; chip is similar in spiritual darkness and evil.
Light thus being created by the Creator, it was good for “God saw all that he had made and behold, very good,” but it got dark by his free will. Myriads of angels sit under it was cut out and followed him and fell with him. So although they were of the same nature with the angels, yet have become bad, and willingly bowing their will from good to bad.
Demons have no dominion, no power against someone, unless he be allowed to God in order to salvation, as is the case with Job and as it is written in the Gospels about pigs. But once God allows, they have power, change and take form it will after their fantasy.
God nor angels nor demons know the future; however prophesying, prophesying angels because God reveals and commands them to prophesy. For everything that is done they say. But the demons prophesy: sometimes because they see what is going on, sometimes by conjecture. Therefore often lie and should not be believed, even if sometimes tell the truth, the way in which we showed. They know, and the Scriptures.
All evil and unclean passions were invented by them. Li was allowed to tempt man, but have no power to force anyone. For we have the faculty to receive temptation or do not receive. For this reason was prepared for the devil and his demons and those who follow him, the unquenchable fire and eternal punishment.
But you must know that what is death for humans, that is for the angels fall. After the fall they have no possibility of repentance, as people do not have any after death.
