I understand what you are saying. But all those writers must be set against scripture. It's like am man asked me one time. How do you tell a crooked stick? You lay a straight one next to it.
You kay the straight stick of scripture against any teaching.
Acts 17:11, "Now these were more noble-minded than those in Thessalonica, for they received the word with great eagerness, examining the Scriptures daily to see whether these things were so."
But ask yourself this - would you "really" feel comfortable with any doctrine where when you ask the hard question of where it is derived - it turns out that it is merely the tradition, or opinion of "your paster, teacher, parent, friend"?
What "if" you dig down on a given doctrine and find that it rests "not" in scripture - but in the tradition/story/preference/bias of a friend, teacher/parent/pastor?
At best - you might hold it at arms length - accept it but not like "For in Six days the Lord Created the Heavens and the Earth" thundered from the mouth of God at Sinai.
But lets push the case further - What if while resting on the strength of "their bias alone" it is found to "contradict scripture"!
Basically you have to bring yourself to the point of "Trusting scripture" enough so that if the word of man contradicts "the Bible alone" - the word of man - goes.
In essence - that is "Sola Scriptura" as applied to "doctrinal validation".
If anything turns out to contradict scripture, of course it should always be tossed out.
What "if" you dig down on a given doctrine and find that it rests "not" in scripture - but in the tradition/story/preference/bias of a friend, teacher/parent/pastor?
We would definitely have to do away with the Trinity, one of the most fundamental teachings of the Christian faith.
We would also have to hold at an arms length the canon of scripture.
You don't have to, because it is so fundamental to the scriptures as a whole, none-the-less, the scriptures do not directly, or even indirectly share anything about a "trinity"
