The Early Church Reached Consensus on Positions That You Reject

There are criteria that you can look to. One of them is apostolicity. So almost every New Testament book is either written by an apostle or someone who's closely associated with an apostle. The only real struggle there is Hebrews, depending on who you think the author of Hebrews is. I would say- Would you agree the early church reached consensus on positions that you reject? No. It depends on how early. Let's say the time of the fourth century by Nicaea and councils of Hippo and Carthage.
