What a "proper Christian" should or shouldn't do I wouldn't know. What sect is that anyway?
As for me I'm a Catholic who has a great regard for science, faith and mathematics.
Perhaps you should write more clearly. When you write that the Bible says that pi is a rational number that is nonsense not supported by any facts. You should be ashamed as a "proper" whatever the heck you are for bearing false witness, no?
I Kings 7:23 And he made a molten sea, ten cubits from the one brim to the other: it was round all about, and his height was five cubits: and a line of thirty cubits did compass it round about.
If a literalist is willing to say man was made whole and evolution never occurred then they are hypocrites if they reject the notion that the proper ratio of a diameter to a circumference is 3.
‘When you write that the Bible says that pi is a rational number that is nonsense not supported by any facts.’
Well besides the Bible actually saying it is so. Have you ever read the thing?
