saved. We seem to have turned full circle. Now it appears that virtuous pagans like Virgil can indeed be saved after all. But this simply raises further questions. Why hasn't Virgil been saved? Why is he still stuck in Limbo?

Dante's ambiguity is a reflection of contemporary theological debates. A number of medieval thinkers such as Thomas Aquinas believed that an individual could be saved despite only having implicit faith in Christ. In other words, those who'd lived before Christ, or those living in remote parts of the globe beyond the reach of Christendom, could still be saved through the free operation of divine grace. On this reading, it was both arrogant and presumptuous to dismiss out of hand the possibility of virtuous pagans being saved, as this would diminish God's power in effecting salvation.

The purpose of Dante's travels through Hell, Purgatory and Paradise is to give him (and, consequently, the reader) the instruments to understand the nature of sin and the extent of its pervasiveness in the poet's society. This produces a tension between Dante as the author (who is fully conscious of this) and Dante as the pilgrim and main character of the work whose knowlege of sin increases with his encounters. This project of offering a comprehensive vision of sin also accounts for the encyclopedic nature of The Divine Comedy. Only by knowing sin and the different forms it takes, can Dante and his readers avoid it, thus bringing about their own salvation.
