In the Orthodox Church, the Holy Chrism is sanctified for use in the celebration of the sacrament of Chrismation. It is a visible sign of the transmission of gifts of the Holy Spirit to those who are baptized.
During the early years of Christianity, the transmission of the gifts of the Holy Spirit to the baptized were given by the Apostles through the “laying of hands.” It is stated in the Scriptures that, “Now when the Apostles at Jerusalem heard that Samaria had received the word of God, they sent to them Peter and John, who came down and prayed for them that they might receive the Holy Spirit, for it had not yet fallen on any of them, but they had only been baptized in the name of the Lord Jesus. Then they laid their hands upon them and they received the Holy Spirit.” (Acts 8:14‑17, R.S.V.)
When the Church spread throughout the world and the number of the baptized was greatly increased, it was not possible to continue the practice of Samaria. Consequently, the Apostles introduced the use of the sanctified Chrism. The Holy Chrism was sanctified by the Apostles and was continued thereafter by the bishops through the Apostolic Succession. The “laying on of hands” was completely replaced by the Holy Chrism to transmit gifts of the Holy Spirit.
The use of the Holy Chrism was introduced to the Christian Church from the existing Old Testament practice. It is stated that, “The Lord said to Moses, ‘Take the finest spices ‑‑ 12 pounds of liquid myrrh, 6 pounds of sweet‑smelling cinnamon, 6 pounds of sweet cane, and 12 pounds of cassia (all weighted according to official standard). Add one gallon of olive oil, and make a sacred anointing oil, mixed like perfume.”’ (Exodus 30:22‑25) (Excerpted from “The Sanctification of the Holy Chrism” by Pavlos Menesoglou)
And about your laughing at me and calling me “Christian,” you know not what you are saying. First, because that which is anointed is sweet and serviceable, and far from contemptible. For what ship can be serviceable and seaworthy, unless it be first caulked [anointed]? Or what castle or house is beautiful and serviceable when it has not been anointed? And what man, when he enters into this life or into the gymnasium, is not anointed with oil? And what work has either ornament or beauty unless it be anointed and burnished? Then the air and all that is under heaven is in a certain sort anointed by light and spirit; and are you unwilling to be anointed with the oil of God? Wherefore we are called Christians on this account, because we are anointed with the oil of God. (To Autolycus 1.12)
Tertullian ca. 160-220
After this, when we have issued from the font, we are thoroughly anointed with a blessed unction,–a practice derived from the old discipline, wherein on entering the priesthood, then were wont to be anointed with oil from a horn, ever since Aaron was anointed by Moses. Whence Aaron is called “Christ,’ from the ‘chrism, ‘which is ‘the unction;’ which, when made spiritual, furnished an appropriate name to the Lord, because He was ‘anointed’ with the Spirit by God the Father; as written in the Acts: ‘For truly they were gathered together in this city against Thy Holy Son whom Thou hast anointed.’ Thus, too, in our case, the unction runs cornally, (on the body,) but profits spiritually; in the same way as the act of baptism itself too is carnal, in that we are plunged in water, but the effect spiritual, in that we are freed from sins. (On Baptism 7)
St. Hippolytus of Rome ca. 170-235
‘And she said to her maids, Bring me oil.’ For faith and love prepare oil and unguents to those who are washed. But what were these unguents, but the commandments of the holy Word? And what was the oil, but the power of the Holy Spirit, with which believers are anointed as with ointment after the layer of washing? All these things were figuratively represented in the blessed Susannah, for our sakes, that we who now believe on God might not regard the things that are done now in the Church as strange, but believe them all to have been set forth in figure by the patriarchs of old, as the apostle also says: ‘Now these things happened unto them for ensamples: and they were written for our instruction, on whom the ends of the world are come.’ (Commentary on Daniel)
St. Cyprian of Carthage died ca. 258
It is also necessary that he should be anointed who is baptized; so that, having received the chrism, that is, the anointing, he may be anointed of God, and have in him the grace of Christ. Further, it is the Eucharist whence the baptized are anointed with the oil sanctified on the altar. But he cannot sanctify the creature of oil, who has neither an altar nor a church; whence also there can be no spiritual anointing among heretics, since it is manifest that the oil cannot be sanctified nor the Eucharist celebrated at all among them. But we ought to know and remember that it is written, ‘Let not the oil of a sinner anoint my head,’ which the Holy Spirit before forewarned in the Psalms, lest any one going out of the way and wandering from the path of truth should be anointed by heretics and adversaries of Christ. (To Januarius, Epistle 70/69:2)
Council of Carthage VII ca. 256
[I]n the Gospel our Lord Jesus Christ spoke with his divine voice, saying, ‘Except a man be born again of water and the Spirit, he cannot enter the kingdom of God’ [John 3:5]. This is the Spirit which from the beginning was borne over the waters; for neither can the Spirit operate without the water, nor the water without the Spirit. Certain people therefore interpret [this passage] for themselves wrongly, when they say that by imposition of the hand they receive the Holy Ghost, and are thus received, when it is manifest that they ought to be born again [initiated] in the Catholic Church by both sacraments. (Seventh Council of Carthage)
St. Aphrahat the Persian ca. 270-345
But a gate has been opened for seeking peace, whereby the mist has lifted from the reason of the multitude; and light has dawned in the mind; and from the glistening olive, fruits are put forth, in which there is a sign of the sacrament of life, by which Christians are perfected, as well as priests and kings and prophets. It illuminates the darkness, anoints the sick, and leads back penitents in its secret sacrament. (Treatises, 23:3)
Council of Laodicea ca. 364
They who are baptized must after Baptism be anointed with the heavenly chrism, and be partakers of the Kingdom of Christ. (Canon 48)
St. Ephrem the Syrian ca. 306-373
That oil is a friend
of the Holy Spirit, and His servant.
Like a disciple, it accompanies Him,
that with which the priests and the anointed are sealed.
By means of the oil, the Holy Spirit impresses
His seal upon the sheep;
Like a signet pressed in wax,
He impresses His seal.
So also the invisible eal of the Spirit
is impressed on our bodies with the oil
With which we are anointed in Baptism,
whereby we bear His seal.
(Hymns on Virginity 7.6)
St. Cyril of Jerusalem ca. 313-386
…[B]eware of supposing this to be plain ointment. For as the Bread of the Eucharist. after the invocation of the Holy Ghost, is mere bread no longer, but the Body of Christ, so also this holy ointment is no more simple ointment, nor so to say common, after invocation, but it is Christ’s gift of grace, and, by the advent of the Holy Ghost, is made fit to impart His Divine Nature. Which ointment is symbolically applied to thy forehead and thy other senses; and while thy body is anointed with the visible ointment, thy soul is sanctified by the Holy and life-giving Spirit. (Catechetical Lectures 21.3)
St. Serapion of Thmuis fl. ca. 330 to 360
You may effect in this chrism a divine and heavenly operation, so that those baptized and anointed in tracing with it of the sign of the saving cross of the Only-begotten, through which cross Satan and every adverse power is turned aside and conquered, as if reborn and renewed through the bath of regeneration, may be made participants in the gift of the Holy Spirit, and confirmed by this seal, may remain firm and immovable, unharmed and inviolate. (Prayer over the Chrism)
St. Basil of Caesarea ca. 330-379
Moreover we bless the water of baptism and the oil of the chrism, and besides this the catechumen who is being baptized. On what written authority do we do this? Is not our authority silent and mystical tradition? Nay, by what written word is the anointing of oil itself taught? And whence comes the custom of baptizing thrice? And as to the other customs of baptism from what Scripture do we derive the renunciation of Satan and his angels? Does not this come from that unpublished and secret teaching which our fathers guarded in a silence out of the reach of curious meddling and inquisitive investigation? (On the Holy Spirit 27.66)
St. Gregory the Theologian ca. 329-389
But if you would fortify yourself beforehand with the Seal, and secure yourself for the future with the best and strongest of all aids, being signed both in body and in soul with the unction, as Israel was of old with that blood and unction of the firstborn at night that guarded him, Exo. 12:22 what then can happen to you, and what has been wrought out for you? Listen to the Proverbs.
If you sit, he says, you shall be without fear; and if you sleep, your sleep shall be sweet. Prov. 3:24 And listen to David giving you the good news,
You shall not be afraid for the terror by night, for mischance or noonday demon. This, even while you live, will greatly contribute to your sense of safety (for a sheep that is sealed is not easily snared, but that which is unmarked is an easy prey to thieves), and at your death a fortunate shroud, more precious than gold, more magnificent than a sepulchre, more reverent than fruitless libations, more seasonable than ripe firstfruits, which the dead bestow on the dead, making a law out of custom. Nay, if all things forsake you, Lk. 9:60 or be taken violently away from you; money, possessions, thrones, distinctions, and everything that belongs to this early turmoil, yet you will be able to lay down your life in safety, having suffered no loss of the helps which God gave you unto salvation. (Oration 40 On Holy Baptism 15)
St. Ambrose of Milan ca. 339-397
After this, you went up to the priest, consider what followed. Was it not that of which David speaks:
Like the ointment upon the head, which went down to the beard, even Aaron’s beard? This is the ointment of which Solomon, too, says:
Your Name is ointment poured out, therefore have the maidens loved You and drawn You. Songs 1:2 How many souls regenerated this day have loved You, Lord Jesus, and have said:
Draw us after You, we are running after the odour of Your garments, Songs 1:3 that they might drink in the odour of Your resurrection.
Consider now why this is done, for
the eyes of a wise man are in his head; Eccl. 2:14 therefore the ointment flows down to the beard, that is to say, to the beauty of youth; and therefore, Aaron’s beard, that we, too, may become a chosen race, priestly and precious, for we are all anointed with spiritual grace for a share in the kingdom of God and in the priesthood. (On the Mysteries 6.29-30)
Blessed Jerome ca. 347-420
Don’t you know that the laying on of hands after baptism and then the invocation of the Holy Spirit is a custom of the Churches? Do you demand Scripture proof? You may find it in the Acts of the Apostles. And even if it did not rest on the authority of Scripture the consensus of the whole world in this respect would have the force of a command. For many other observances of the Churches, which are due to tradition, have acquired the authority of the written law, as for instance the practice of dipping the head three times in the layer, and then, after leaving the water, of tasting mingled milk and honey in representation of infancy; and, again, the practices of standing up in worship on the Lord’s day, and ceasing from fasting every Pentecost; and there are many other unwritten practices which have won their place through reason and custom. So you see we follow the practice of the Church, although it may be clear that a person was baptized before the Spirit was invoked. (Against the Luciferians 8)
Blessed Augustine of Hippo ca. 354-430
Why, therefore, is the Head itself, whence that ointment of unity descended, that is, the spiritual fragrance of brotherly love,–why, I say, is the Head itself exposed to your resistance, while it testifies and declares that “repentance and remission of sins should be preached in His name among all nations, beginning at Jerusalem”? And by this ointment you wish the sacrament of chrism to be understood, which is indeed holy as among the class of visible signs, like baptism itself… (Letters of Petilian the Donatist, Bk. 2,104:239)
Apostolic Constitutions compiled ca. 375
But thou shalt beforehand anoint the person with the holy oil, and afterward baptize him with the water, and in the conclusion shall seal him with the ointment; that the anointing with oil may be the participation of the Holy Spirit, and the water the symbol of the death of Christ, and the ointment the seal of the covenants. But if there be neither oil nor ointment, water is sufficient both for the anointing, and for the seal, and for the confession of Him that is dead, or indeed is dying together with Christ. (Apostolic Constitutions, 7,2:22)
St. Cyril of Alexandria ca. 376-444
The living water of holy Baptism is given to us as if in rain, and the Bread of Life as if in wheat, and the Blood as if in wine. In Addition to this there is also the use of oil, reckoned as perfecting those who have been justified in Christ through holy baptism.(Commentary on the Minor Prophets, 32)
St. Patrick of Ireland ca. 387-493
The day after the newly baptized, anointed with chrism, in white garments (had been slain) – the fragrance was still on their foreheads when they were butchered and slaughtered with the sword by the above-mentioned people – I sent a letter with a holy presbyter whom I had taught from his childhood, clerics accompanying him, asking them to let us have some of the booty, and of the baptized they had made captives. They only jeered at them. (Letter to Coroticus)
Pope St. Leo the Great ca. 400-461
Today’s festival, dearly-beloved, hallowed by the descent of the Holy Ghost, is followed, as you know by a solemn fast, which being a salutary institution for the healing of soul and body, we must keep with devout observance. For when the Apostles had been filled with the promised power, and the Spirit of Truth had entered their hearts, we doubt not that among the other mysteries of heavenly doctrine this discipline of spiritual self-restraint was first thought of at the prompting of the Paraclete in order that minds sanctified by fasting might be fitter for the chrism to be bestowed on them. The disciples of Christ had the protection of the Almighty aid, and the chiefs of the infant Church were guarded by the whole Godhead of the Father and the Son through the presence of the Holy Ghost. (Sermon 78)
St. Dionysius the Areopagite ca. 5th cent.
…[T]he priests guide the man to the water and there he is handed over to the hierarch who, standing on a more elevated spot, immerses three times the initiate whose name is called out across the water by the priests to the hierarch with each immersion. Each time the initiate is plunged into the water and emerges, the hierarch invokes the three Persons of the divine blessedness. The priests then bring the man back to his sponsor, to the one who had brought him for introduction, and together with him they reclothe the man and bring him back once more to the hierarch. Using the most potently divine ointment he makes the sign of the cross on him and proclaims him ready to participate in the sacredly initiating Eucharist. (The Ecclesiastical Hierarchy Chap. 2)
Pope St. Gregory the Dialogist ca. 540-604
It has also come to our ears that some have been offended by our having forbidden presbyters to touch with chrism those who are to be baptized. And we indeed acted according to the ancient use of our Church: but, if any are in fact hereby distressed, we allow that, where there is a lack of bishops, presbyters may touch with chrism, even on their foreheads, those who are to be baptized. (Letters Bk. 4.26)
Bede the Venerable ca. 673-735
The spiritual anointing is the Holy Spirit Himself, whose sacrament is the visible anointing. He says that all who have this anointing of Christ perceive good and evil and do not need to be taught, because the anointing it self teaches them.(Commentary on 1st John)
St. John Damascene ca. 676-749
Olive oil is employed in baptism as a significant of our anointing, and as making us anointed, and as announcing to us through the Holy Spirit God’s pity: for it was the fruit of the olive that the dove brought to those who were saved from the flood. (An Exposition of the Orthodox Faith Bk. 4.9)
Council of Trullo ca. 692
Those who from the heretics come over to orthodoxy, and to the number of those who should be saved, we receive according to the following order and custom. Arians, Macedonians, Novatians, who call themselves Cathari, Aristeri, and Testareskaidecatitæ, or Tetraditæ, and Apollinarians, we receive on their presentation of certificates and on their anathematizing every heresy which does not hold as does the holy Apostolic Church of God: then first of all we anoint them with the holy chrism on their foreheads, eyes, nostrils, mouth and ears; and as we seal them we say—
The seal of the gift of the Holy Ghost. (Canon 95)
