Hyrule really does has a faith that is totally it's own.
Link is savior figure in his own right. Everything he does serves to protect and inspire the people around him, and he does it all out of generosity and unbound courage. Conversely Ganondorf IS the embodiment of evil, he's deceitful, cruel and a bit cowardly. My personal favorite inspirational Link moment is the cut scenes and story surrounding Dodongo's Cavern. Sometime prior to Link arriving at death mountain for the first time, Ganondorf was had already paid a visit. He no doubt demanded the Goron's Ruby be handed over to him, presumably under threats of violence. The Goron's refuse to yield. Ganondorf then seals the entrance to Dodongo's Cavern threatening the very livelihood of Gorons (mining rocks to eat, and stuff to make bombs to sell). Link, however, blasts the cave open, and then proceeds to clear the infestation of monsters out of the cavern, all with little though of reward. The Goron's show their appreciation to Link by giving him the Goron's Ruby and making him an honorary brother.
The Triforce itself is simply an artifact of Power. For you see, courage and wisdom in and of themselves can be very powerful, but it's a different kind of power from the raw physical power represented by the triforce of Power.
Perhaps, though, Majora's Mask is the most powerfully symbolic of all the Legend of Zelda's, as
this article demonstrates (click me). (It was posted before, but it's a really good read, worth posting again since the subject became appropriate, used it as source for an essay on philosophy in video games for my writing class last semester.) I can't put how awesome this article is in words, you have to read it for yourself.
The best thing is that Zelda promotes it's philosophy without promoting a faith. (I tend to thing that religions only cause more problems than they solve, yeah, I'm atheist.) Virtues expressed in the Legend of Zelda are universal. Courage, Kindness, Determination, Observation, and Problem Solving skills are all just good things to have.
