Yes but i haven't delved very far into them..
There is a reason for that.. much of what I read seems very worldly, this pope didn't like that pope who didn't think this pope blah blah blah .
So caring all the whys and wherefore were rather.. I don't know just didn't seem important. Church history reads like a soap opera.
What was important to me was learning Scripture.
The Seven Ecumenical Councils all occurred between 325 and 787 AD. There wasn't any "this pope didn't like that pope" involved in any of them, for one, because there was no "pope" as we understand that term today.
The First Council of Nicea addressed the Arian controversy, and asserted that Jesus Christ is of the same Being as the Father, truly God.
The First Council of Constantinople addressed the Pneumatomachi or Macedonian controversy, they are sometimes known as Semi-Arians; they denied the Deity of the Holy Spirit. As such the Council asserted that the Holy Spirit is Lord and God, and reaffirmed the creed drawn up at Nicea, amending it to include a longer statement about the Holy Spirit: that we believe "in the Holy Spirit, the Lord and Giver of life, who proceeds from the Father, and who with the Father and the Son is worshiped and glorified. He spoke through the prophets."
The Council of Ephesus addressed the Nestorian controversy, and sided with Cyril of Alexandria that Christ was one Hypostasis and Person.
The Council of Chalcedon addressed the Eutychian controversy, asserting that the one indivisible Person of Jesus Christ is both truly God and truly man, without any confusion of His two natures. Drawing up the Definition of Chalcedon.
The Second Council of Constantinople had some lofty goals, but had some other side effects. The sum of what it accomplished is perhaps best said that it reaffirmed the previous two Councils of Ephesus and Chalcedon; which in turn did not exactly help in any future hope of reconciling the
Persian Church (which considered Theodore of Mopsuestia one her major theological doctors, he was condemned here), and it didn't accomplish the intended goal of reconciling the Non-Chalcedonian Churches (
the Oriental Orthodox). But is largely remembered for its reaffirmation of Chalcedonian Christology.
The Third Council of Constantinople addressed the Monothelite controversy. The Monothelites were a kind of "soft" Monophysite. They accepted the Diaphysite position of Chalcedon (Jesus has two natures in His one Person), but they argued that Jesus had one will (mono "one" + thelo "will"), a Divine will. This council again reaffirmed the position of Chalcedon and insisted that Jesus, on account of His two natures, had two wills, human and Divine, but that these will were always united and in agreement, without any confusion, without conflict.
The Second Council of Nicea addressed the Iconoclast controversy. The Byantine Empire at the time had been suffering losses at the hands of the Muslim armies, and Emperor Leo sought to understand why the Romans were losing and the Ummayads (and Abbasids after them) winning; Leo concluded that it was because the Muslims did not use sacred images in their religion. So Leo banned sacred images, and sought to have them destroyed (Iconoclast = eikon "image" + klaein "smash" or "break"). This met with considerable (and obvious) pushback from the Church. And this council asserted that images of Christ and the saints were not in violation of the commandment against making graven images of God, since Christ was human, and obviously the saints are human; but that images of the Father and the Holy Spirit are not acceptable since God is, in His Essence, invisible and incomprehensible, and we can only see and meet God face to face in the Person of the Son: Jesus.
These are the Seven Ecumenical Councils. There were other councils, mostly local synods; and there were councils that were embraced by some and not others, but when people talk about the Seven Ecumenical Councils it's these, and that's it. And none of them had to do with the pope. In fact all of them took place in the Christian East, not the West; and the only major contribution from the Bishop of Rome I am aware of is the Second Council of Constantinople with the Tome of St. Leo.
