Ohhhh - I get it now....because one is a noun and the other is a verb you cannot manage to make the relational connection between “believe” and “belief”, let me help you:
What one believes is their belief
You believe Darwin existed; therefore, that Darwin existed is your belief.
As such, according to you, any discussions of Darwin, by you, should remain only in church. You don’t follow your own demands - you should remove your tagline, and should never have mentioned Darwin on this forum. KEEP YOUR BELIEFS IN CHURCH!!!
The main difficulty in achieving my goal has been to know what to leave out. The Origin marks the foundation of modern biology, and of large parts of geology as well. I have tried to reflect its breadth and have, no doubt, failed. My own volume tries to use Darwin's logic to illuminate the discoveries of today. It is not a history of evolutionary ideas, or of life; nor a biography of Darwin, or of animals and plants, but an argument that will, I trust, persuade my readers of the truth of evolution.
From Proverbs, we have ...
"Those who are wise store up knowledge, but the mouth of a stubborn fool invites ruin."
