The other "evidence" you speak of falls into the category of unreliable due to it either being mistaken evidence or fabricated evidence in my opinion.
According to what Abdul-Baha said it is to do all three. Have you read this?;
This whole chapter is on the need for an educator. Here are the relevant points;
"...education is of three kinds: material,
human and spiritual."
"
Human education signifies civilization and progress—that is to say, government, administration, charitable works, trades, arts and handicrafts,
sciences, great inventions and discoveries and elaborate institutions..."
"Now we need an educator who will be at the same time a material,
human and spiritual educator, and whose authority will be effective in all conditions."
"Therefore, the Universal Educator must be at the same time a physical,
human and spiritual educator; and He must possess a supernatural power"
"Now we must consider justly: did these Divine Manifestations Who have appeared possess all these qualifications or not?
3 If They had not these qualifications and these perfections, They were not real Educators"
"It has now been proved by rational arguments that the world of existence is in the utmost need of an educator, and that its education must be achieved by divine power. There is no doubt that
this holy power is revelation"
So you see according to Abdul-Baha they did come to educate us in the sciences through the power of revelation.
Contradictions don't balance each other out. If I say the sun gives light and the sun does not give light, this does not mean that the sun gives half light for example. When Abdul-Baha was saying "Any religion that contradicts science or that is opposed to it, is only ignorance" he was talking to people of other religions, when he spoke to Baha'is he always corrected them on matters of science by insisting on what he saw as revealed truth. Therefore it is clear that he wanted other religions to be subject to science to eradicate their superstitions, but *not* the Baha'i faith in my view.
Physician heal thyself. I believe that the whole picture is that Shoghi Effendi interprets the words of Abdul-Baha. And he said, "You see our
whole approach to each matter is based on the belief that God sends us divinely inspired Educators; what they tell us is fundamentally true, what science tells us today is true; tomorrow may be entirely changed to better explain a new set of facts." To try and "balance" that by focusing on a tiny portion of a quote from Abdul-Baha's numerous contradictory quotes and actions is not looking at the "whole" picture or as Shoghi Effendi says the "
whole approach"
I understand that it was not dishonest. The way I see it you got confused, threw out an ad-hominem, and can't support the substance of your ad-hominem so are now doubling down on your ad-hominem and hand waving the need to support your claim which is a serious allegation.
