I always noted that the so-called "ecumenical catholic councils" did not begin with this first Church-wide Apostolic decision, but rather only the one called by emperor Constantine. That right there shows a self-admitted discontinuity between the apostles and the later Church.
Officially, yes, from Constantine. ( 313-325 Nicean Council period)
But the Secular church which will start to persecute the true believers was lurking from the time of 251 AD when Fabian died in Rome, and there was a split between 2 groups,
one pursuing the quick and rapid growth of the church by accepting the apostates who yileded to the Idolatry during the persecution, headed by Cornelius, believing that the more people with bigger building means the great success in the Gospel ministry and the apostate should be accepted as long as they repented, condemning the others who do not accept the "repented Apostates-idol worshippers during the persecution" as the hypocrites. They must have accepted the new comers as long as they accept the teachings, without serious testimony of the belief.
the other group who tried to keep the faith strictly to be faithful with Lord, believing that the growth and the success of the church means that the true believers bear the fruits according to the teachings of Bible, not the increase of buildings and numbers of people, avoiding the sins, refusing the apostates who betrayed the Lord during the persecution unless they showed the great change and the repentance to endure any persecution if they encounter such persecution next time, headed by Novatian. They accepted only the truly born again believers as their members, then the number of the church people was not increased very fast.
Eventually the first group led by Cornelius succeeded in the business of increasing the people, very much able and competent in managing the people and building, and a type of church easy for the unbelievers to participate in without repentance or serious agony, no need to be broken-hearted. These type of people are very much concerned about the buildings and property when they split each other.
The second group may have regarded the buildings and the properties not as important, and gave them up, and quickly became the minor group in the city of Rome.
Then the first group started to condemn the second group led by Novatian as a Cult or Heretics! The Cornellius group would have been called "Orthodox".
Then they started to pray for the Empire, for the Emperor referring to Romans 13. They eventually pursue the State-Church and started to persecute the true believers as long as they had the power.
Roman Catholic is nothing but the transformation or the extension of Roman Empire which persecuted the Truue Christians, transformed into the Religion which is full of Paganism. This kind of State-Church needed to call for the Council to instruct the One-Way human made instructions.
Though some portion of above mentioned history is added by myself personally for better understanding, but the basic structural development was the same as we see the church development today.
We can find this kind of development in the history if we dig out further.
