Quod ubique, quod semper, quod ab omnibus credituni est
This is the oft repeated maxim of Vincent of Lerins, a semi-Pelagian from the 5th century, translated as "what has been believed everywhere, always, and by all". Used as a definition of Christian orthodoxy, it presents an ecumenical embrace of Christian doctrine that has its focus on the bare essentials of the Christian faith. It removes ecclesiastical dogma as the harbinger of salvation. Subscribing to this maxim, we cannot embrace several key doctrines as central to salvation and acceptance within the Christian community. The Calvinist acrostic TULIP could not be embraced as within the veil of orthodoxy established by the Vincentian Canon. Neither could certain aspects of the Arminian doctrine of Prevenient grace. There are traditions and creeds from several otherwise orthodox sects within the body of Christ that we cannot embrace as orthodoxy itself if we embrace Vincent's perspective.
If Vincent's maxim is received as presented, can we reject semi-Pelagianism as being outside the essential fold of Christian doctrine and therefore its adherents as unredeemed? The Augustinian doctrine of Grace and man's fallen condition oppose the semi-Pelagian notion of assisted inherency and Vincent was certainly opposed to Augustine's teachings on these matters. Yet, so were a great many others prior to Augustine's conflicts with Pelagiaus. It might be objected that Vincent argued a self interest although that alone does not negate his premise regarding orthodoxy. Instead, one must demonstrate that the exclusion of doctrine from the embrace of orthodoxy is done so with damage to essential soteriology as determined within scripture, this also being Vincent's premise. Can Oneness Pentecostalism be regarded as orthodox with regard to soteriology yet heterodox regarding the Godhead? Are Pelagians within the scope of justification? Do we consider intellectually driven high Calvinists with their notions of the Gospel defined as Calvinism to be fair game on the evangelical field?
