Material Signs of Spiritual Realities
The sacramental principle — that God works through physical means to convey spiritual grace — is not an invention of the medieval Church. It is the operating principle of the entire Old Testament. God uses oil, water, blood, bread, gesture, and word to do things that only God can do.
A sacrament is an outward sign instituted by God to give grace. The definition applies to most of what God does in the Old Testament. He fills the Tabernacle with his glory through smoke and fire. He cleanses through water. He strengthens through bread and water (Elijah). He communicates authority through the laying on of hands. He anoints kings and priests with oil that transforms them. He speaks through human prophets whose words are his words. The New Testament sacraments do not introduce a new principle; they concentrate and complete one that was already operating.
Three Old Testament institutions are treated here. Each corresponds to a cluster of New Testament sacraments: anointing prefigures Confirmation and Anointing of the Sick; the blessing gesture prefigures priestly absolution and blessing; the prophetic word prefigures the sacramental power of the ordained minister to speak in the person of Christ. Together they show that the sacramental economy of the Catholic Church has Old Testament roots as deep as any other element of Catholic doctrine.
Anointing of Kings and Priests — The Seal of the Spirit
Oil is the Old Testament's primary sacramental element. The anointing of a king or priest does not merely designate them; it transforms them. Something happens to the person anointed that changes their capacity to act in their new office.
1 Samuel 10:1, 6: Samuel anoints Saul, and the text records: "the Spirit of the Lord will rush upon you, and you will prophesy… and be turned into another man." 1 Samuel 16:13: Samuel anoints David, and "the Spirit of the Lord rushed upon David from that day forward." The anointing with oil is the instrument of the Spirit's coming. The person is genuinely changed; they become capable of what they were not capable of before.
Exodus 29:7; Leviticus 8:12: Aaron and his sons are anointed to consecrate them for priestly service. The oil marks the transition from ordinary Israelite to consecrated priest. The anointing is not merely ceremonial; it constitutes the priesthood.
Christ (Anointed One) is anointed with the Holy Spirit at his baptism (Acts 10:38: "God anointed Jesus of Nazareth with the Holy Spirit and with power"). He then anoints his followers: "you have been anointed by the Holy One" (1 John 2:20). Confirmation is the New Covenant anointing: the chrism is oil, and what the oil confers is the gift of the Spirit for the Christian's mission in the world.
James 5:14-15 records the anointing of the sick with oil as an apostolic practice, with the promise that "the Lord will raise him up." The anointing with oil for healing continues the Old Testament pattern of oil as the instrument of divine action in the physical world.
The anointing types show that the Catholic use of oil in Confirmation and the Anointing of the Sick is not a medieval accretion. It follows the Old Testament pattern of oil as the instrument of the Spirit's action, which continues through the New Testament and into the sacramental practice of the earliest Church. Tertullian documents the practice at AD 198, citing the Old Testament anointing as its precedent.
The Lifting of Hands in Blessing — Priestly Benediction
The Aaronic blessing of Numbers 6 is the oldest liturgical formula in continuous use in the world. It is still prayed in synagogues, in Catholic and Protestant churches, and over Jewish children on Sabbath evenings. Its structure prefigures both priestly absolution and sacramental blessing.
Numbers 6:22-27: God instructs Moses to tell Aaron and his sons to bless Israel with specific words: "The Lord bless you and keep you; the Lord make his face shine on you and be gracious to you; the Lord turn his face toward you and give you peace." God then adds: "So they shall put my name on the people of Israel, and I will bless them." The priest's words are not merely a wish; they are the vehicle by which God puts his name on his people. The blessing does what it says.
Luke 24:50-51: Christ's last gesture before the Ascension is to lift his hands and bless his disciples. He does not give a farewell speech; he raises his hands in the Aaronic gesture and bestows a blessing. The disciples return to Jerusalem with great joy. The blessing is real and effective.
The sacramental absolution of the Catholic priest follows the same pattern: the priest raises his hand, speaks words in the first person ("I absolve you"), and what is said is done. The priestly word is not merely declaratory; it is performative, because the priest speaks in the person of Christ who gave him the authority to bind and loose (Matthew 18:18; John 20:23).
The blessing type is most useful in explaining the Catholic doctrine of ex opere operato: that the sacraments work by virtue of the rite itself (performed correctly and with right intention) rather than by the personal holiness of the minister. Numbers 6:27 establishes this: God says "I will bless them" when the priests speak the words, not "I will bless them if the priests are holy enough." The efficacy is God's, transmitted through the ordained instrument.
The Prophet — The Word of God in Human Speech
The Old Testament prophet speaks not his own words but God's. The formula "Thus says the Lord" is not a literary convention; it is a theological claim. When the prophet speaks, God speaks. This pattern prefigures the capacity of the ordained minister to act and speak in persona Christi.
Deuteronomy 18:18: "I will raise up for them a prophet like you from among their brothers. And I will put my words in his mouth, and he shall speak to them all that I command him." The prophet's mouth is the instrument of God's speech. What the prophet says, God says. When Jeremiah delivers a judgment, the judgment is God's. When Isaiah announces consolation, the consolation is God's.
The prophetic capacity is not a permanent personal possession; it is given for specific occasions and withdraws. The prophet speaks God's words; he does not replace God or possess God's authority independently.
Christ is the prophet who fulfils Deuteronomy 18 (Acts 3:22; 7:37). He speaks not from his own authority but from the Father's (John 12:49-50). He then delegates this capacity to his apostles: "Whoever receives you receives me, and whoever receives me receives him who sent me" (Matthew 10:40). "As the Father has sent me, even so I am sending you" (John 20:21).
The ordained priest at the Mass does not say "this is the body of Christ"; he says "this is my body" — in the first person, in the person of Christ. The prophetic principle reaches its sacramental apex in the words of institution: a human voice, speaking Christ's words, in which Christ's body and blood become present. The instrument is human; the action is divine.
The prophetic type grounds the Catholic understanding of ministerial authority in the most fundamental category of Old Testament theology: the authorized human speaker of divine words. To object that a human priest cannot speak in the person of Christ is to object to the prophetic principle itself. If God put his words in the mouths of Jeremiah and Isaiah, he can put them in the mouths of those to whom Christ delegated his apostolic commission.
The Sacramental Principle Is Ancient
The three types treated here share a common structure: God works through physical instruments and human persons to accomplish spiritual ends. Oil transforms kings and priests. The priest's words put God's name on the people. The prophet's mouth is the channel of God's speech. In every case, the created element or the human person is genuinely effective — not merely symbolic — because God has chosen to work that way.
The Catholic sacramental system does not add a layer of religious ceremony to the Gospel. It continues the operating principle of the whole of Scripture: that the God who spoke creation into existence, who parted the sea with a rod, who anointed kings with oil, who put his words in the prophets' mouths, continues to work through the physical, the particular, and the ordained. The sacraments are not human inventions added to a pure spiritual religion. They are the form in which the religion has always, from Genesis onward, actually existed.
The God of the Old Testament never treats the physical world as an obstacle to spiritual reality. He uses it. He speaks through burning bushes, parts water with wind, feeds his prophet with angel-bread, anoints leaders with oil, and puts his name on his people through a human voice. The New Testament sacraments are not a departure from this pattern. They are its culmination: the same God, still working through the physical, now working through the flesh, death, and resurrection of his Son, and through the sacramental life of the Church he left behind.
