As Christians how can we distinguish between what is definite (Doctrine - supported by scripture and global historical church), what is less clear ( Controversy) and what is plain wrong ( Heresy)?
What process should we follow to establish the veracity of God centred truth claims?
Authority is at the centre of all of the disputes between protestant and catholic, catholic and orthodox even
"by what authority" can we know?
Complicated by the questions
- that Scripture does not state its own exclusivity, indeed points to the church and tradition outside of itself as the "foundation of truth" indeed asks that disputes are taken to the church.
- That scripture does not interpret itself. Without dwelling on the differences, there are mutually exclusive views of more or less every aspect of doctrine from baptism eucharist moral issues, salvation end times etc etc all using the same scripture to decide opposite doctrines! You are either OSAS, Saved can lose it, or not saved till the end. You can only be one of those- they are alternative! So sola scriptura has resulted in myriads of conflicting doctrine.
- that the new testament as we know it, did not exist in early church, and was a product of the authority of the church, that is the councils - so tradition was the only mechanism prior to that.
So most probably know the catholic position.
- that the apostolic succession (ie bishops appointed in succession) were tasked with handing down true doctrine, and resolving conflicts.
- by reading the early fathers we see that and true doctrine in action (take Ignatius to smyrneans - taught by john the apostle ) on the need for bishops for valid eucharist of the real flesh.
- that the successors of apostles (jointly) and Peter (individually) are given the power to "bind and loose" which means give definitive rulings on doctrine - it is that power wielded by councils.
- which is why disputes are brought to the church "the pillar and foundation of truth" which is stated as the "household of God"
- that primacy of Rome is seen in such as Iraneus (who also speaks of decision on heresy (gnosticism) modalism, even the first false canon of Marcion rejected.
- We see that later with the bishops declaring the primacy of Rome , the tome of Leo "there speaks peter", indeed augustine lists all the popes as authority in his argument against donatism
But it boils down to.
- tradition (paradosis) handing down of the whole faith by succession
- authority to "bind and loose" in council which rejected arianism and approved the creed and new testament
- same authority given to, but rarely if ever used by successors of Peter - the popes primary role is chief pastor "tend my sheep"
The problem for NONE catholics is....if you decide the fathers at council were not acting with authority, then how can you accept the new testament? (which was as much rejecting other books claimed as apostolic authorship as it was a process of inclusion) - and since those fathers such as anasthasius - key in the arguments against arianism, aslo believed in intercession of mary, and eucharistic transformation to real flesh at the blessing... If you accept the new testament how can you reject what the fathers said it meant?
That was the problem that set me on my journey from protestantism, through evangelical to catholicism. Finding authoirty in early church.
