Hi DawnBringer... and welcome, as I haven't met you yet.

I'm not actually going to say anything about whether it's right/wrong... I'm going to leave more experienced fantasy writers to give you their thoughts on that.

But as a not-fantasy-writer but very-much-fantasy-reader, I'd like to give you my perspective on the appearance of this idea.
If I get what you're saying, the basic concept here is that there is one God in your world, and He created these lesser 'god' beings who
are nature, and the sources of different qualities and values; Sol, Luna, Terra, and Jesus.
It's an interesting idea, and without really analyzing it, two things stick out in my mind.
The main one is that you seem to be placing Jesus on a par with the other 'gods'... making Him less than God when He is God, even though you've placed Him as leader of the three lesser gods. I'd be really careful of this, because He is God in every sense of the word, equal with the Father, existing before the creation of the world.
Second thing that struck me is that both by using the word 'god' and using these lesser gods as the 'sources' of different qualities and as Nature itself... you could be at risk of confusing a portrayal of Christianity with elements of ancient religions etc. Let me explain:
The idea of having them each represent an attribute of the one true God reminds me of the religion of ancient Egypt. Each ancient Egyptian god took care of a different aspect of life or was a different aspect of nature, and G.A Henty puts forth in his historical fiction the idea that some of the Egyptians might have actually worshiped God through worshiping His attributes in these figure-head gods, which I find unacceptable. Not saying that you're doing this, but ideas like this can easily occur to the reader.
Second thing... you know how you were saying that the gods are the living, breathing, forces of nature? In this you've given non-living matter
personality... and here is the danger of accidentally and indirectly affirming that age-old idea of 'Mother Nature'. The idea that nature is actually a
personality with some vague form of antiquated and unconscious intelligence. I've actually heard of one atheist explaining the design apparent in creation this way. Anyway, it can also have patheistic connotations, so I'd be careful with this.
And your reference to C S Lewis... he was an awesome writer. But there are some things that I don't appreciate in his writing. One is his use of pagan ideas in a book portraying Christianity. If you see what I'm saying, it can get messy and confusing very easily, and portray a false picture of Christianity to those who don't know Biblical doctrine so well.
I think... perhaps change the name of these 'gods'.... maybe even make them archangels in charge of certain aspects of creation... I don't know. But it seems to me that you're kind of making these gods too 'big'... there's not enough distinction between them and God.
Hope you find this helpful.

The others are far more experienced in tackling and using concepts and ideas such as these so I bet they'll have some awesome suggestions. But this is how it appears to me just as reader, at present.
By the way, in the fantasy I've written, I've always been loathe to name Jesus, for the same reason. What I found helpful was using different variation of His name. Remember that Christ is also Immanuel (God with us). Once I used a shortened variation... Manuel. So that's another idea.
