Prayer of St. Mary of Egypt to the Theotokos

O Virgin, Mother of God, who didst give birth to God the Word, I know that it is neither fitting nor seemly that one so defiled and so covered with guilt as I should look up to thy image, O ever Virgin. It is fitting that I should be hated and shunned by thy purity. Yet as He who was born of thee became man on purpose to call sinners to repentance, help me, for I have no other succour. Let me also find an entrance. Do not refuse me a sight of the wood on which God the Word, thy Son, suffered according to the flesh, who shed His own precious blood for me. Grant, O Queen, that I may be admitted to worship the sacred Cross, and I will promise thee as surety to the God whom thou didst bring forth that I will keep myself ever undefiled, When I see the Cross of thy Son, I will at once renounce the world and the things of the world, and forthwith follow wherever thou shalt lead.”

St. Sophronius of Jerusalem
The Life of St. Mary of Egypt

Those who are imaged are real and help us

With the material picture before our eyes we see the invisible God through the visible representation, and glorify Him as if present, not as a God without reality, but as God who is the essence of being. Nor are the saints whom we glorify fictitious. They are in being, and are living with God; and their spirits being holy, they help, by the power of God, those who deserve and need their assistance.

Part III, Quote from Simeon of Mount Thaumastus

God’s holy ones are worshipped as partakers of the divine nature

And “God stood in the synagogue of the gods; in the midst of it He points out the gods.” (Ps. 82.1) As, then, they are truly gods, not by nature, but as partakers of God’s nature, so they are to be worshipped, not as worshipful on their own account, but as possessing in themselves Him who is worshipful by nature. Just in the same way iron when ignited is not by nature hot and burning to the touch, it is the fire which makes it so. They are worshipped as exalted by God, as through Him inspiring fear to His enemies, and becoming benefactors to the faithful. It is love of God which gives them their free access to Him, not as gods or benefactors by nature, but as servants and ministers of God. We worship them, then, as the king is honoured through the honour given to a loved servant. He is honoured as a minister in attendance upon his master— as a valued friend, not as king. The prayers of those who approach with faith are heard, whether through the servant’s intercession with the king, or whether through the king’s acceptance of the honour and faith shown by the servant’s petitioner, for it was in his name that the petition was made. Thus, those who approached through the apostles obtained their cures. Thus the shadow, and winding-sheets, and girdles of the apostles worked healings. (Acts 5.15) Those who perversely and profanely wish them to be adored as gods are themselves damnable, and deserve eternal fire. And those who in the false pride of their hearts disdain to worship God’s servants are convicted of impiety towards God. The children who derided and laughed to scorn Elisseus bear witness to this, inasmuch as they were devoured by bears. (II Kgs. 2.23)

…I venerate and worship angels and men, and all matter participating in divine power and ministering to our salvation through it.

…No one should be worshipped as God except the one true God. Whatever is due to all the rest is for God’s sake.

Part III, What We Find Worshipped in Scripture

There are many unwritten traditions that are handed down

The eye-witnesses and ministers of the word handed down the teaching of the Church, not only by writing, but also by unwritten tradition. Whence comes our knowledge of the sacred spot, Mount Calvary, of the holy sepulchre? Has it not been handed down to us from father to son? It is written that our Lord was crucified on Calvary, and buried in the tomb which Joseph hewed out of the rock, but it is unwritten tradition that teaches us we are adoring the right places, and many other things of the same kind. Why do we believe in three baptisms, that is, in three immersions? Why do we adore the Cross? Is it not through tradition? Therefore the holy apostle says: “Brethren, stand fast; and hold the traditions which you have learned, whether by word, or by our epistle.” (II Thess. 2.15) Many things, therefore, being handed down to the Church by unwritten tradition and kept up to the present day, why do you speak slightingly of images?

I am not to be persuaded that the Church is set in order by imperial edicts, but by patristic traditions, written and unwritten. As the written Gospel has been preached in the whole world, so has it been an unwritten tradition in the whole world to represent in image Christ, the incarnate God, and the saints, to adore the Cross, and to pray towards the east.

Solomon’s temple, like the Church, was decorated by images

The temple which Solomon built was consecrated by the blood of animals, and decorated by images of lions, oxen, and the palms and pomegranates. Now, the Church is consecrated by the blood of Christ and of His saints, and it is adorned with the image of Christ and of His saints.

The Saints are deserving of honor

For if the friends of Christ are heirs of God and co-heirs of Christ, and are to be partakers of the divine glory and kingdom, is not even earthly glory due to them? I call you not servants, our Lord says; you are my friends. Shall we, then, withhold from them the honor which the Church gives them?

The relics of the Apostles were miraculous so shouldn’t the Saints be glorified?

…the image of Him who is visible to flesh is burnt into my soul. The shadow and winding sheet and relics of the apostles cured sickness, and put demons to flight. (Acts 5.15) How, then, shall not the shadow and the statues of the saints be glorified?

The images of the Saints are honored in the Church

We depict Christ as our King and Lord, and do not deprive Him of His army. The saints constitute the Lord’s army. Let the earthly king dismiss his army before he gives up his King and Lord. Let him put off the purple before he takes honor away from his most valiant men who have conquered their passions. For if the saints are heirs of God, and co-heirs of Christ, (Rom. 8.17) they will be also partakers of the divine glory of sovereignty. If the friends of God have had a part in the sufferings of Christ, how shall they not receive a share of His glory even on earth? “I call you not servants,” our Lord says, “you are my friends.” (Jn. 15.15) Should we then deprive them of the honor given to them by the Church?

Sanctification is a participation in the whole Trinity

For, in this way, he who is such as his Creator wished him to be, will receive from God power always to exist, and to abide for ever.  That this may be the case, and that those whom He has created may be unceasingly and inseparably present with Him, Who IS, it is the business of wisdom to instruct and train them, and to bring them to perfection by confirmation of His Holy Spirit and unceasing sanctification, by which alone are they capable of receiving God.  In this way, then, by the renewal of the ceaseless working of Father, Son, and Holy Spirit in us, in its various stages of progress, shall we be able at some future time perhaps, although with difficulty, to behold the holy and the blessed life, in which (as it is only after many struggles that we are able to reach it) we ought so to continue, that no satiety of that blessedness should ever seize us; but the more we perceive its blessedness, the more should be increased and intensified within us the longing for the same, while we ever more eagerly and freely receive and hold fast the Father, and the Son, and the Holy Spirit.  But if satiety should ever take hold of any one of those who stand on the highest and perfect summit of attainment, I do not think that such an one would suddenly be deposed from his position and fall away, but that he must decline gradually and little by little, so that it may sometimes happen that if a brief lapsus take place, and the individual quickly repent and return to himself, he may not utterly fall away, but may retrace

By the grace of the Holy Spirit and our free will we participate in Christ

Having made these declarations regarding the Unity of the Father, and of the Son, and of the Holy Spirit, let us return to the order in which we began the discussion.  God the Father bestows upon all, existence; and participation in Christ, in respect of His being the word of reason, renders them rational beings.  From which it follows that they are deserving either of praise or blame, because capable of virtue and vice.  On this account, therefore, is the grace of the Holy Ghost present, that those beings which are not holy in their essence may be rendered holy by participating in it.  Seeing, then, that firstly, they derive their existence from God the Father; secondly, their rational nature from the Word; thirdly, their holiness from the Holy Spirit,—those who have been previously sanctified by the Holy Spirit are again made capable of receiving Christ, in respect that He is the righteousness of God; and those who have earned advancement to this grade by the sanctification of the Holy Spirit, will nevertheless obtain the gift of wisdom according to the power and working of the Spirit of God.
