There's plenty of history in this world that is not recorded in Scripture. But in dealing with issues concerning Christianity, it is THE standard by which truth claims are to be measured.
And to demand that something be taken as dogma or doctrine, as a truth that must believed by the faithful else they risk their salvation, there must be more substantiation than hearsay.
Surely if the Holy Spirit thought that the doctrine was necessary for us to know pertaining to salvation, then He would have seen fit to put it in there Himself.
But He didn't, so I don't see where anyone else, no matter who they claim to be, has any authority to make it binding on believers for salvation.
Well, just for starters, according to the authority we both share --- the Bible ---who has the power to bind and loose?
Matthew 16:19
And I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.”
Matthew 18:18
“Assuredly, I say to you, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven."
Who's He talking to here? Who has this power in your church?
