This is a road-marker or a sign post for the church of England. Your faith is not evolving it's eroding. Concerning survival of the fittest: your faith is not strong enough for you to survive. You've classified theory as fact and the basic tenets of your faith as theory. Your foundations have been destroyed. If you turn back to the scriptures and seize upon its teachings and make them your foundation rather than the theories of the age then your faith will be well-founded and your chances of surviving will return. If you let every theory challenge and destroy your faith you're just like sand on the seashore and every wave degrades you. I believe the Lord's arms are outstretched to you desiring you to turn to Him, but if you reject His Word then you surely have rejected Him. Those who truly believe the Word of God and act on it will have an abundant harvest of souls to present to our King, Jesus Christ, and all you will have is empty buildings.
Blessings on you
