Well, if we take into considerations these two refferences:

But, said Lewis, myths are lies, even though lies breathed through silver. No, said Tolkien, they are not. And, indicating the great trees of Magdalen Grove as their branches bent in the wind, he struck out a different line of argument.
You call a tree a tree, he said, and you think nothing more of the word. But it was not a ‘tree’ until someone gave it that name. You call a star a star, and say it is just a ball of matter moving on a mathematical course. But that is merely how you see it. By so naming things and describing them you are only inventing your own terms about them. And just as speech is invention about objects and ideas, so myth is invention about truth.
We have come from God (continued Tolkien), and inevitably the myths woven by us, though they contain error, will also reflect a splintered fragment of the true light, the eternal truth that is with God. Indeed only by myth-making, only by becoming a ‘sub-creator’ and inventing stories, can Man aspire to the state of perfection that he knew before the Fall. Our myths may be misguided, but they steer however shakily towards the true harbour, while materialistic ‘progress’ leads only to a yawning abyss and the Iron Crown of the power of evil.

and keeps the rags of lordship once he owned,
his world-dominion by creative act:
not his to worship the great Artefact,
man, sub-creator, the refracted light
through whom is splintered from a single White
to many hues, and endlessly combined
in living shapes that move from mind to mind.
Though all the crannies of the world we filled
with elves and goblins, though we dared to build
gods and their houses out of dark and light,
and sow the seeds of dragons, 'twas our right
(used or misused). The right has not decayed.
We make still by the law in which we're made.

So, I would say the myths represent to him a spiritual path, which redeems us; this may not be the same thing with Christianity, but I doubt that for him, God/Truth was any other than the biblical one.
