Jesus Christ
Ἰησοῦς Χριστός — Iesous Christos · ee-ay-SOOS khris-TOSS
In brief
Jesus Christ is the eternal Son of God become man — one person, fully God and fully human. Everything in Orthodox faith hangs on Him: the world was made through Him, salvation is union with Him, the Church is His Body, and history ends at His return. "Jesus" is a name — in Hebrew, "the Lord saves" — and "Christ" is a title: the Anointed One, the Messiah promised to Israel. Together they are already a confession: the Savior God promised has come, and He is the Lord Himself.
The question and the confession
At Caesarea Philippi, Christ asked His disciples the question on which everything turns: who do you say that I am? Simon Peter answered: "Thou art the Christ, the Son of the living God" (Matthew 16:16). That confession is the rock on which the Church stands. Orthodoxy has never been content to call Jesus a great teacher, a prophet, or a moral example — He is those things, but the Gospels will not let anyone stop there. He forgives sins as only God can, and He speaks of Himself in words no creature may use: "Before Abraham was, I am" (John 8:58).
This means that in Jesus, God is not sending a message; He is coming in person. "He that hath seen me hath seen the Father" (John 14:9). Whatever we could guess about God from creation or conscience, in Christ we no longer have to guess — the invisible God has a human face, a human voice, human wounds. The apostle calls it "the mystery of godliness: God was manifest in the flesh" (1 Timothy 3:16).
True God and true man
The Church spent her first centuries defending both halves of Peter's confession, because every early heresy trimmed one of them. Arianism made Him less than fully God; Docetism made His humanity a costume; Nestorianism so divided the God from the man that the one Christ threatened to become two; Eutyches let His humanity be swallowed by His divinity. Against all of these the Fourth Ecumenical Council at Chalcedon in 451 confessed one and the same Christ, "perfect in Godhead and also perfect in manhood; truly God and truly man" — one person in two natures, neither confused nor separated, united in what the Church calls the hypostatic union.
The Church fought for this with such stubbornness because salvation depends on it. Only God can save us; only as man can He reach us. The eternal Word took our whole nature from the Theotokos — body, soul, mind, and will — so that everything human might be healed from the inside. Cut either nature and the bridge collapses: a Christ who is not God cannot lift us to God, and a Christ who is not man never truly touched us.
His work, and where He is now
The Creed tells His story as a single sweep: for us and for our salvation He came down, was made flesh, was crucified, rose, and ascended. Orthodoxy reads that story less as a legal transaction than as a rescue and a healing — the strong Son of God entering the enemy's territory, trampling down death by death, and carrying human nature up to the right hand of the Father. The tradition sums up His work in three offices: prophet, priest, and king — the Truth who teaches, the Priest who offers Himself, the King who reigns.
And He is not a figure of the past. The risen Christ is present now — in His Body the Church, in the Holy Mysteries, in the least of His brethren, and in every heart that calls on His name. Orthodox life is simply life in Him: baptized into His death and resurrection, fed with His Body and Blood, awaiting His return. The last prayer of the Bible is addressed to Him — — come, Lord Jesus — and every Liturgy is celebrated in that same expectation of His coming.
