From what I recall of that theory both the Earth and moon were rendered completely molten by the impact. (Obviously, since they both ended up round.) It is doubtful that any intact biological material would survive such conditions. Water is all over the place in the universe, so there not being water on the moon would be much more significant. For instance, Earth is hit by icy meteorites almost every day, so one would expect the moon to receive similar treatment.
As for the religious aspect, the lack of effect finding life on the moon would have on religious faith brings up the question of what *would* affect religious faith. If there is no situation that would cause a believer to stop believing then faith becomes more of a condition than a conclusion.

Liquid water seems limited to Earth, but H2O appears to be out there in significant amounts.
Your source conveniently skips Saturn's moon Europa, which has a thin atmosphere composed mostly of oxygen and significant indications of a liquid ocean under its icy crust. Tidal flexing could maintain volcanic vents leading to life similar to what lives around oceanic vents on Earth.

While water may be a necessary condition for life, it doesn't at all follow that water is a sufficient condition for life. The moon may or may not have water on it, but it certainly seems to be lacking in other elements necessary for life to emerge.
Necessary for life as we know it. There may be living things out there that do not require water to live, or are comfortable in conditions in which our life cannot function.
In any case, I believe the significance of the discovery is that it makes a moon base that much easier to bring about. A base will need a water supply, and the more materials you can get at your destination the less you have to bring with you.
