[Religion] Unintentional Religion in Tolkien's works?

I know that this has been touched on in several other posts, so I will be brief.
I think that when someone strongly adheres to or believes in a certain belief system or set of moral standards then it is evident in the way that person talks, acts, writes, etc. Since Tolkien was a rather devout Catholic, I think that it would make sense for his beliefs and standards to come out in his writings.

Now for a few other questions and comments:

onewhitetree wrote, "Ea is more comparable to Greek and Roman legend than Christianity when it comes to demigods and patron caretakers."
I'd like to propose another spin to this - take it or leave it. I had wondered if it wasn't the Catholic influence of the patron Saints that was the inspiration for such beings as the Maiar and Valar.

Arwen Imladris wrote, "Would mythology be a better word to describe it?"
I was just wondering what the word "it" was referring to.
