All you need is love.
Sorry, the Ecumenical Counsels is a fact of history. They voted to decide what the Bible would be as a set collection, and all others rejected, most destroyed.
Wait, you just denied it happened.
Yeah, they decided what was to be included, and throw out the rest. The story about how Revelations made it in the final cut is interesting. It came down to some bishops trading votes for favored books. Not exactly a rigid system that ONLY assessed "inspired by God", whatever that meant. It's funny that mere mortals can decide what is inspired by God and what isn't, as if they are Gods themselves.
Of course the whole motivation was to create one source for Christians so there can be a consistent dogma to teach, and legalize Christianity and unify all the little sects that existed under the rulke of Constantine. Arguably this was political, to create stability.
According to the Bible, the Holy Spirit dwells within the people who believe in Jesus (Ephesians 1:13–14; 4:30), not only corroborating to them that they belong to God and are saved (Romans 8:15–17; 10:9–13; 1 Corinthians 12:13), but also endowing them with some spiritual gifts (1 Corinthians 12:4-11) and spiritual discernment to correctly understand the Bible (1 Corinthians 2:14). However, if the Holy Spirit resides within all of the followers of Jesus and gives them spiritual discernment to correctly understand the Bible, then wouldn't Christians from all over the world agree on a single interpretation of the Bible?
In my opinion, if all Christians had this spiritual discernment to correctly understand the Bible, then the Catholic Bible (with a 73-book canon), the Greek Orthodox Bible (with a 79-book canon), and the plethora of various Protestant Bible translations (with a 66-book canon) would not exist. There would be a single correct interpretation of the Bible and one unified universal Christian Church. However, this is clearly not how it is within Christianity because it is vastly divided into Messianic Jews, Anglicans, Catholics, Orthodox (Eastern Orthodox, Oriental Orthodox, Ethiopian Orthodox, Greek Orthodox), and a vast variety of Protestants: Baptist (First Baptist, Second Baptist, Southern Baptist, Reformed Baptist, Primitive Baptist, Anabaptist, Freewill Baptist), Methodist, Lutheran, Pentecostal, Mennonite, Church of Christ, Presbyterian, Seventh-day Adventist, Non-Denominational, and hundreds of other Protestant churches.
