It is a common LDS belief that Christianity fell into apostasy because of the corruption of Greek philosophy. By the fourth century, Christian theologians had rearticulated the beliefs and understandings of Christian orthodoxy using the substance and techniques of philosophy, with most of the resource being that of a popular version of Platonism. The statements of belief and the defenders of those statements make that unmistakable. However, it has become clear that the assimilation of Hellenistic philosophical tradition into Christianity was the consequence—not the cause—of the apostasy as we understand it.
Prior to the arrival of Clement of Alexandria and during the first 150 years of Christianity, references to contemporary philosophies by Christians were clearly limited to dealings with outsiders. But guess who was coming to dinner and staying? Following a tradition going back to Paul (Acts 17:18-31), missionaries would allude to beliefs of philosophers contemporary to their time as a means of introducing their own message. This was an attractive strategy where the philosophically literate community shared with the Christians sincerity about living a excellent life defined by a rejection of the vulgar excesses of pagan worship and the folly of pagan mythology. Christian apologists, such as Justin Martyr, found the philosophical beliefs of the Roman elites most useful on which to articulate their own Christianity.
But Clement took a much bigger step near the end of the second century when he consciously adopted the rational methods of philosophy as the tools of Christians in pursuit of the truth. While this philosophical strategy was never uncontroversial, it spread rapidly throughout the Christian community and was both officially and firmly established by the fourth-century councils that produced the Christian creeds.
The interesting discovery for Latter-day Saints comes when they realize that traditional Christians—Protestant, Catholic, and Eastern—regard this adoption of Hellenist philosophy as the salvation of the incomplete and struggling Christian community.
Clement was consciously following the example of the Jewish philosopher Philo of Alexandria, who had written volumes in the decades just before Christ's ministry in which he systematically allegorized the Old Testament bringing it into accord with a contemporary form of Platonism.
We must remember the world was a much larger place at this time where most Christians depended upon oral tradition to exchange newer truths. By the last two decades of the second century, not only had all the authorized apostles and prophets “disappeared”, but the first generation of Christians who had the benefit of knowing and hearing them were also gone. Lacking faithful witnesses, those authoritative voices who clarified scriptural uncertaintiesleft a void. Christians became ever more lost to the philosophies of men for divine direction for their new life challenges.
If the philosophical pontifications found at blogstream seem distant from simple common sense biblical truths, know by what tradition they come.
