What was the point of the first seven ecumenical councils if the Pope had already made a ruling?
I suggest you haven’t sufficiently studied ecclesial history. Councils gathered to discuss doctrinal or disciplinary matters. After the council, the decisions and canons are either ratified or rejected by the Bishop of Rome. This does not mean that the pope “already made a ruling.” How could he ratify or veto canons and ecclesial documents that have yet to be formulated and decided upon by council?
On the contrary, the ecumenical councils only become “ecumenical” by ratification of the pope. Thus, the council precedes the ratification. Furthermore, only those councilar decisions and canons that are ratified by the pope have binding force.
The
Council of Chalcedon, for example, was attended by prelates of the Bishop of Rome. They were sent by the Bishop of Rome to Chalcedon to represent him. At the council, the prelates of Rome objected to canon 28, but the canon was voted upon and the prelates of Rome were out-voted by the other bishops. Nonetheless, after the council, the bishops of Chalcedon sent a letter to Pope Leo asking the pope to ratifiy the canons of Chalcedon.
From the letter to Pope Leo from the Bishops of Chalcedon:"You are set as an
interpreter to all of the voice of blessed Peter, and to all you impart the blessings of that Faith. … (Chalcedon to Pope Leo, Ep 98)Besides all this, he (Dioscorus, Bishop of Alexandria) extended his fury even against him
who had been charged with the custody of the vine by the Savior. We refer to Your Holiness. … (ibid)Knowing that every success of the children rebounds to the parents, we therefore
beg you to honor our decision by your assent, and as
we have yielded agreement to the Head in noble things, so may the
Head also fulfill what is fitting for the
children. (ibid) Thus, the bishops of Chalcedon understood the pope to be the “head” of the college of bishops, with authority to either ratify or veto the decisions voted upon in Council.
Notice that the Eastern and Western Bishops of Chalcedon are asking for Pope Leo’s ratification of their councilar decisions, yielding their agreement to the “HEAD” of the Church. Note that they consider themselves “CHILDREN” to Pope Leo. Also note that they assert that Pope Leo had been charged with “CUSTODY OF THE VINE
BY THE SAVIOR” and not by political gain or the mere consent of the other bishops.
These claims agree with Catholicism. Pope Leo undoubtedly had singular juridic authority to either ratify or to reject the councilar decisions. No other bishop was asked to ratify the councilar decision, because no other bishop had been charged with “custody of the vine by the Savior.”
So, what did Pope Leo do? There were 28 canons decided upon at Chalcedon. Pope Leo ratified all of them except canon 28, which attempted to elevate Constantinople with wording that was contrary to Catholic teaching. Pope Leo exercised his VERY REAL juridic authority and rejected canon 28. Subsequently,
Anatolius, the Bishop of Constantinople, wrote to Pope Leo, and apologetically stated,"As for those things which the universal Council of Chalcedon recently ordained in favor of the church of Constantinople [ie. canon 28], let Your Holiness be sure that there was no fault in me, who from my youth have always loved peace and quiet, keeping myself in humility. It was the most reverend clergy of the church of Constantinople who were eager about it, and they were equally supported by the most reverend priests of those parts, who agreed about it.
Even so, the whole force of confirmation of the acts was reserved for the authority of Your Blessedness. Therefore, let Your Holiness know for certain that I did nothing to further the matter, knowing always that I held myself bound to avoid the lusts of pride and covetousness.(Patriarch Anatolius of Constantinople to Pope Leo, Ep 132, on the subject of canon 28 of Chalcedon)The evidence of history is clear. Pope Leo had juridic authority to veto that which an Ecumenical Council of Bishops agreed to. Only the Bishop of Rome has ever exercised this clear jurisdictional authority in the history of Christianity. Did Pope Leo “preside” only in honor or did he have real authority to either ratify or reject councilar decisions? It seems clear the latter is true, contrary to the opinion of later revisionists. Why did Pope Leo have this authority? The bishops of both East and West at Chalcedon in the fifth century asserted as the Catholic Church asserts today: the pope has been charged with the custody of the Vine by the Savior.
