What Did The First Four "Ecumenical" or Universal Councils of the Christian Church Teach About Jesus
Nearly all Christian, of whatever church, acknowledge the authority and truth of the teachings of the first four "great councils" (also called "ecumenical" or worldwide councils) of early Christianity. This is because these Councils clarified (and, for some, defined) what the Christian scriptures taught and what the early church believed about God, Jesus and Mary. Some of the great leaders of early Christianity affirmed the importance of these councils, such as St. Augustine (354-430) who compared the authority of the ecumenical councils with that of the apostles, and St. Gregory the Great (540-604) who said: "I confess that I accept and reverence the four Councils as I do the four Gospels… for they are founded on universal consent."
What did these councils teach? The Council of Nicaea in 325 AD responded to the claim of a priest of Alexandria, Arius, that the Word or Son of God (who "became flesh and dwelt among us" as Jesus - Jn 1:14) was not God and hence was not eternal; he did not always exist. Arius argued on the basis of some Gospel passages that Jesus never claimed that he was God, as when he says in the Gospel of John (14:28) that "the Father is greater than I."
The bishops at Nicaea considered all the pertinent texts of the Gospels (such as Jn 10:30: "I and the Father are one") and concluded that Arius was wrong. The Son or Word of God is God (see Jn 1:1) and always existed. To clarify this they proclaimed a creed (the "Nicene creed") which included a key Greek word, homoousios, which meant that the Word or Son is of the same "being" as God the Father. If the Father is God, so is the Son. If the Father is eternal, almighty (and so on), so is the Son or Word of God.
Tragically, a few bishops after the Council of Nicaea questioned the decision of the Council (saying, for instance, that homoousios is an unscriptural word), and convinced the Roman emperor and his sons that Arius and his beliefs had been wrongly condemned. It took over fifty more years of controversy before the First Council of Constantinople (381 AD) reaffirmed the teaching and the creed of Nicaea. This ecumenical council also added a phrase to the Nicene Creed to affirm the divinity or Godhead of the Holy Spirit, the "Lord and Giver of Life" who with the Father and the Son "is worshiped and glorified". Thus by the end of the fourth century the Christian belief in God as a Trinity of three equal divine persons: Father, Son and Holy Spirit, was formally recognized by Christians.
In the fifth century there were two more ecumencal councils that addressed questions about Jesus. In the early 5th century a prominent bishop, Nestorius, rejected the title "theotokos" or "God-bearer" to refer to Mary. Christians believed that the mother of /Jesus could rightly be called the "Mother of God" or "God-bearer" because the Gospel clearly teaches that Jesus was conceived in Mary, not by any human being, but by the Holy Spirit. This was what the angel Gabriel announced to Mary one day in Nazareth (the "Annunciation") and Mary consented (see Lk 1:26-38). Nestorius thought that to call Mary "Mother of God" would confuse people into thinking that the eternal God came into being through a human. The Council of Ephesus met in 431AD to consider Nestorius’ opinion. The Council decided that it was right and good to honor Mary as "Mother of God" because she is the mother of God in his human nature. The Council clarified that Mary "contributed" to Jesus his true and full humanity, while God the Holy Spirit "overshadowed" Mary so that the child born to her was truly God, the Son or Word of God (Lk 1:30-35).
This belief that Jesus is both human and divine, man and God, led to much debate and speculation after the Council of Ephesus about how this mystery could be expressed. A monk, Eutyches, living in Constantinople claimed that before Jesus took flesh in Mary there were two "natures" (a divine and human nature), but after the union of the two natures in Mary’s womb there was only one nature in Jesus - the divine nature. In a sense Eutyches proposed that the nature of God is so great that it overshadows and "swallows up" the humanity of Jesus. For Eutyches, Jesus took on human appearance, but the only full and true nature remaining in Jesus after taking on "flesh" (the outward human appearance) is the nature of God. To put it simply, Eutyches’ claim is that Jesus was truly God, but not truly or fully human.
The bishop of Constantinople, Flavian, objected to this. He wrote a letter to the bishop of Rome, Pope Leo I, to get this opinion, as well. Unfortunately, due to Church politics a council was called with the emperor Theodosius II’s consent in 449 AD that proclaimed Eutyches’ position (called "Monophysitism") correct, and deposed Bishop Flavian. The letter of Pope Leo in response to Flavian was ignored by this council. But things changed quickly. Theodosius II died suddenly (he fell off his horse) and his sister, Pulcheria, prevailed upon her husband, the new emperor Marcian, to call another council to reconsider the issue. The Council of Chalcedon was called in 451 AD. This time Pope Leo’s letter was read and all positions were fairly considered. The result was the formulation of a creed of the Council of Chalcedon that declared that Jesus Christ is one person who exists "in two natures" - a divine nature and a human nature - which are neither confused ("blended together" into a third nature) nor divided or separated (so Jesus is not "schizophrenic" - sometimes acting like God, sometimes like a man). Jesus is one person who is truly and fully God and truly and fully human. How this can occur is beyond our comprehension. It is truly what Christians mean by the term "mystery": not something unreasonable; just something beyond human capacity to understand fully. Hence it must be accepted not by reason alone, but also by faith.
The first four ecumenical Councils defined the meaning of the basic Christian beliefs about God and Jesus Christ that were proclaimed by the Church in her teaching, tradition (beliefs "handed down"), and sacred writings. They are necessary even today to know what most Christians believe about these central issues.

Nicaea (in modern Turkey);
Emperor Constantine I (the Great)
325
Traditionally 318 bishops but probably closer to 220-250;
the elderly Pope Sylvester was represented by several priests.
Is the Son who became flesh in Jesus Christ divine in the same sense as the Father? This was denied by the priest Arius of Alexandria and his followers.
How to set the date of Easter and some issues relating to Church discipline.
The bishops formulated a creed affirming the belief that the Son is God in the same sense as the Father. All but two bishops approved the creed. However, after the Council, supporters of Arius with influence at the imperial court engineered his rehabilitation which guaranteed the continued dissemination of his teaching.
Constantinople (modern Istanbul);
Emperors Theodosius I and Gratian
381
About 150 bishops, all from the East (but the Council was later accepted in the West)
Pope Damasus was unrepresented.
Continuing heresies of the Arians and semi-Arians, including the denial of the full divinity of the Holy Spirit.
Precedence of the Patriarch of Constantinople over all other Patriarchs except the Bishop of Rome.
The rejection of all Arian opinions and the affirmation of the divinity of the Holy Spirit as reflected in the creed now known as the Niceno-Constaninoplitan Creed which is the one used in the liturgy to this day.

Relation of Christ’s divine and human natures provoked by a debate whether Mary should be called Mother of God (Theotokos) or only Mother of Christ (Christokos).
The affirmation that the one person of the Son of God exists in two natures, as God and as man. This is called the hypostatic/personal union - the union of the two natures in the one hypastasis/person of the Son.
The Council confirmed that the title "Theotokos" is appropriate for the Blessed Virgin Mary.

Christ’s divine and human natures, in particular over against those who claimed that his divine nature absorbed his human nature.
Matters of church discipline relating to clergy and the jurisdiction of bishops, etc.
The creedal formulation which declares in part, "we all unanimously teach that … our Lord Jesus Christ is one and the same Son, the same perfect in Godhead and the same perfect in manhood, truly God and truly man…. made known in two natures without confusion, without change, without division, without separation, the difference of the natures being by no means removed because of the union…"
