I don't think that that meeting in Jerusalem meant such a thing. Among the brothers there were some who were weak and did not understand some difficult-to-understand issues. Other brothers surely, like today, resisted changing their Jewish views that they had before becoming Christians, to the point that, for example, some of them insisted on the need for circumcision for Gentiles.
However, even though these differences existed, as happens in some matters that are decided at the level of personal conscience (based on well-known biblical principles on a personal level), what these differences in the first century really demonstrated was the capacity of the holy spirit and the direction of Christ over the newly formed Christian congregation. In what sense?
There was a very intelligent way of clearing up doubts: the elders and apostles of Jerusalem were consulted so that they could find a solution to the matter, as shown in chapter 15 of the book of Acts of the Apostles. Their decision overcame the conflicting opinions and feelings of the different groups of Christians at the time. They all accepted the decision that was made in Jerusalem and that was made known through letters sent and read equally in all the Christian congregations in the area.
Is there any religious organization today that follows this same procedure? Yes; Jehovah's Witnesses follow the same procedure. When a brother around the world has a serious doubt, he sends it to the Governing Body through the appropriate channel and waits for the answer without causing divisions in the congregation, thus avoiding sectarianism, and promoting a common way of thinking among all. That is why Jehovah's Witnesses enjoy the blessings of following this biblically established model.
