Why did Gandalf save Faramir?

Maybe then Gandalf's decision was not a moral one, but there's the added bonus in the story of the author postulating a god. In non-fiction at least it's a classic moral dilemma, but it could lose something in adaptation.

I think the problem here is that you cannot look at The Lord of the Rings as the Arda cosmology.

Tolkien labored his entire career over the Arda cosmology; The Lord of the Rings represented one phase of his literary career.

Eru does not exist in the Lord of the Rings.

I was wrong in saying that the Lord of the Rings is trans-moral. In fact, the morality behind the Lord of the Rings is of a staunchly Catholic variety: a moral battle taking place on a plane on which Deity does not exist; there are, however, three 'transcendental' figures who impose themselves on the narrative: Gandalf, Wisdom; Sauron, Corruption; and Saruman, Wisdom Corrupted.

Then there is the Hobbit: there is no Deity and only a vague allusion to Transcendental force - though there is magic of a childlike variety, to be sure.

Then there is the Silmarillion: it is this piece which is trans-moral, as it presents to us the paradox of Evil as an Illusion which God caused to be.

Gandalf is the link between Trans-Morality and Childhood Faerie Tale: he saves Faramir as a moral act on the earthly plane which exists between the two, because he alone knows the trans-moral implications of sacrificing the lives of others.
