In Christian Renaissance circles, What does this tell us about the origins of the Renaissance?

The following passage comes from medieval thinker Roger Bacon:

The next consideration from effects is taken by comparing our state with that of the ancient Philosophers; who, though they were without that quickening grace which makes man worthy of eternal life, and where into we enter at baptism, yet lived beyond all comparison better than we, both in all decency and in contempt of the world, with all its delights and riches and honors; as all men may read in the works of Aristotle Seneca, Tully [Cicero], Plato, Socrates, and others; and so it was that they attained to the secrets of wisdom and found out all knowledge. But we Christians have discovered nothing worthy of those philosophers, nor can we even understand their wisdom; which ignorance of ours springs from this cause, that our morals are worse than theirs. For it is impossible that wisdom should coexist with sin. But certain it is that, if there were so much wisdom in the world as men think, these evils would not be committed. And therefore, when we see everywhere (and especially among the clergy) such corruption of life, then their studies must needs be corrupt. Many wise men considering this, and pondering on God's wisdom and the learning of the saints and the truth of histories have reckoned that the times of Antichrist are at hand in these days of ours. ~ Roger Bacon ca. 1271
