Regarding arnoldo's citation of Justin Martyr's attack on Greek literature, it should be noted that even though Justin was opposed to believing in the myths of Homer, he was still very familiar with them:
"For first they say that Agamemnon, abetting the extravagant lust of his brother, and his madness and unrestrained desire, readily gave even his daughter to be sacrificed, and troubled all Greece that he might rescue Helen, who had been ravished by the leprous shepherd. But when in the course of the war they took captives, Agamemnon was himself taken captive by Chryseis, and for Briseis' sake kindled a feud with the son of Thetis. And Pelides himself, who crossed the river, overthrew Troy, and subdued Hector, this your hero became the slave of Polyxena, and was conquered by a dead Amazon; and putting off the god-fabricated armour, and donning the hymeneal robe, he became a sacrifice of love in the temple of Apollo. And the Ithacan Ulysses made a virtue of a vice. And indeed his sailing past the Sirens gave evidence that he was destitute of worthy prudence, because he could not depend on his prudence for stopping his ears. Ajax, son of Telamon, who bore the shield of sevenfold ox-hide, went mad when he was defeated in the contest with Ulysses for the amour."
Also, Christians continued to teach Homer well into the fourth century CE even though they didn't believe in it, which prompted the emperor Julian to ban it (and note that he places Homer first in his list of classical writers):
"Was it not the gods who revealed all their learning to Homer, Hesiod, Demosthenes, Herodotus, Thucydides, Isocrates and Lysias? Did not these men think that they were consecrated, some to Hermes, others to the Muses? I think it is absurd that men who expound the works of these writers should dishonour the gods whom they used to honour. Yet, though I think this absurd, I do not say that they ought to change their opinions and then instruct the young. But I give them this choice: either not to teach what they do not think admirable, or, if they wish to teach, let them first really persuade their pupils that neither Homer nor Hesiod nor any of these writers whom they expound and have declared to be guilty of impiety, folly and error in regard to the gods, is such as they declare. For since they make a livelihood and receive pay from the works of those writers, they thereby confess that they are most shamefully greedy of gain, and that, for the sake of a few drachmae, they would put up with anything."

So whether Christians believed it or not, they knew it.
