If you think you now are ready to show me where the Scripture forbids the Church from "binding and loosing" on matters of faith, feel free to resume.
Your "binding and loosing" cite means nothing at all related to the churches use of corruptible and fallible men to determine policy that does not have solid ground in scripture.
As I mentioned before, just one corrupted man on a council destroys the veracity of these non-scriptual pronouncements, like worshiping the dead by praying to them. A little leaven leavenith the whole lump.
Paul said this in reference to the few bad apples among the faithful in the church of Corinth. Paul said this several times, and so did Jesus. Each referred to the small amount of evil among the greater good, and the effect that has on any results.
Same with ecumenical councils of the church.
