In practice, it seems readers of Scripture have been drawing separate conclusions for two millenium now, no? The history of variant opinions on this seems to indicate that the internal evidence is still ambiguous, no matter how much we would like to pretend otherwise.
Origen, I’m sure, had all the best intentions. He was seemingly influenced by a Platonic philosophical worldview, however. We bring our worldviews to Scripture when we read it, and this cannot be helped. The post-reformation worldview was radically different (eg. Hobbsian, existentialism, etc) than that of the first century Christians, so it’s no wonder that there are such a plethora of doctrines that were previously held that are now “uncertain” within reformation-minded Scripture readers.
The best we can do is try to learn what the worldview of the 1st century writers most likely could have been. This demands that we look at internal AND external evidence by looking to contemporary sources, and sources before and immediately following the first century (eg. the Book of Judith, the writings of Irenaeus, Origen, etc.). Admittedly, a very subjective endeavor. However, what seems unambigous is that the Church is the “pillar and foundation of truth” and not necessarily every interpreter of Sacred Scripture and Sacred Tradition. Arius made this very clear in Athanasius’ day. The surest means of sifting through orthodox understandings of Scripture from heterodox or heretical views, was to look to the origen of such teachings. In Athanasius’ view, was the teaching that which was delivered to us by Scripture AND apostolical men? Athanasius asserts that Arius’ view would not have been heretical if apostolical men also taught such a doctrine.
Thus, we obey the leaders charged with the care of our souls (cf. Heb 13:17), just as the circumcisor party ought to have obeyed the decrees sent forth from the council of Jerusalem in the Book of Acts. After which, the case is closed, excepting those who have a rather heterodox understanding of devotion to apostolic teaching.
