Your statement would be true except for one thing - evolution and materialism are deterministic and the Christian religion specifically states that man has free will, so you have it absolutely backwards, like most of what the Darwinists say.
What more necessity can you have than "survival of the fittest" - the central proposition of Darwinism, the Deux ex Machina which allows evolution to replace God as the creator of all things?

Darwinism is not materialism, and darwinism is certainly not deterministic, any more than physics is, in a strict sense. Phenomena in both cases reduce to quantum effects, which can only be understood statistically, until the Heisenburg Uncertainty Principal is repealed.
