We make mention [in the Divine Liturgy] also of the Seraphim, whom Isaiah in the Holy Spirit saw standing around the throne of God, and with two of their wings veiling their face, and with two their feet, while with two they did fly, crying 'Holy, Holy, Holy, is the Lord of Hosts' (Isaiah 6:2-3). For the reason of our reciting this confession of God, delivered down to us from the Seraphim, is this, that so we may be partakers with the hosts of the world above in their hymn of praise.
A prayer offered while one has any cause to reproach a fellow man is an impure prayer. There is only one whom the praying person may and must reproach, and that is himself. Without self-reproach, your prayer is as worthless as it is while you are reproaching someone else in your heart. Perhaps you ask: How can one learn this? The answer is: One learns it through prayer.
But, say the saints, now that you recognize the darkness in your own heart and the weakness of your flesh, you lose all desire to pass judgment on your neighbor. Out of your own darkness you see the heavenly light that shines in all created things reflected the clearer: you cannot detect the sins of others while your own are so great. For it is in your eager striving for perfection that you first perceive your own imperfection. And only when you have seen your imperfection, can you be perfected. Thus perfection proceeds out of weakness.
There are three things that impel us towards what is holy: natural instincts, angelic powers and probity of intention. Natural instincts impel us when, for example, we do to others what we would wish them to do to us (cf. Luke 6:31), or when we see someone suffering deprivation or in need and naturally feel compassion. Angelic powers impel us when, being ourselves impelled to something worthwhile, we find we are providentially helped and guided. We are impelled by probity of intention when, discriminating between good and evil, we choose the good.
Do not the angels differ from us in this respect, that they do not want so many things as we do? Therefore the less we need, the more we are on our way to them; the more we need, the more we sink down to this perishable life.
The Law (as it is written in the Scriptures) was given to us by Angels and, both before and after the days of the Law, Angels guided our illustrious forefathers to God, either by declaring to them what they should do and leading them from error and an evil life to the straight path of truth, or by making known to them the Divine Law, or in the manner of interpreters, by showing to them holy Hierarchies, or secret visions of super-mundane Mysteries, or certain divine prophecies. Now if anyone should say that God has shown Himself without intermediary to certain holy men, let him know beyond doubt, from the most Holy Scriptures, that no man has ever seen, nor shall see, the hidden Being of God; but God has shown himself, according to revelations which are fitting to God, to His faithful servants in holy visions adapted to the nature of the seer.
But if you are fearful of becoming self-righteous from working for your own salvation, or afraid of being overcome by spiritual pride, examine yourself and observe that the person who is afraid of becoming self-righteous suffers from blindness. For he does not see how self-righteous he is.
The dread Mysteries, full of such great salvation, which are celebrated at every Liturgy, are also called a Thanksgiving [Eucharistia] because they are the remembrance of many benefits, and they signify the culmination of God's Providence towards us, and in every way cause us to be thankful to Him.
Be despised and rejected in your own eyes, and you will see the glory of God within yourself. For where humility blossoms, there God’s glory bursts forth.
We know there are Angels and Archangels, Thrones, Dominions, Princedoms, Powers, Splendors, Ascents, Intelligent Powers or Intelligences, pure natures and unalloyed, immovable to evil, or scarcely movable; ever circling in chorus round the First Cause (or how should we sing their praises?) illuminated thence with the purest Illumination, or in one degree or another, proportionally to their nature and rank...so conformed to beauty and molded that they become secondary Lights, and can enlighten others by the overflowings and largesse of the First Light. Ministrants of God's Will, strong with both inborn and imparted strength, traversing all space, readily present to all at any place through their zeal for ministry and the agility of their nature...
As for uprooting your passions, begin with self-reproach and with awareness of your own weaknesses; and consider yourself to be deserving of afflictions.
I wish I could persuade spiritual persons that the way of perfection does not consist in many devices, nor in much cogitation, but in denying themselves completely and yielding themselves to suffer everything for the love of Christ. And if there is failure in this exercise, all other methods of walking in the spiritual way are merely a beating about the bush, and profitless trifling, although a person should have very high contemplation and communication with God.
Whom else does the Lord call by the name of Powers of heaven unless the Angels, the Archangels, the Thrones, Dominions, Principalities, and Powers, who at the coming of the Just Judge will then appear visibly to our eyes, to the end that they may sternly exact an account of that which the Invisible Lawgiver now patiently suffers?
