Early in the twentieth century Abdul-Baha the oldest Son of Baha'u'llah was asked some questions about creation and science at the time and He responded and His responses were translated into English in a book entitled "Some Answered Questions" this book has been in print for almost a hundred years and was recently revised as to a few words in the English translation..But let me state a few principles that Baha'is accept before I share what was more specifically stated about "creation"; "evolution"; etc.
The principle held by Baha'is is that science and religion should be in harmony.. As we are all aware there has been a struggle in European circles between science and religion.. a separation for sure and an antagonism between them. So the following are a translation of the words of Abdul-Baha on the issue between science and religion:
"Religion and Science are inter-twined with each other and cannot be separated. These are the two wings with which humanity must fly. 29 One wing is not enough. Every religion which does not concern itself with Science is mere tradition, and that is not the essential. Therefore science, education and civilization are most important necessities for the full religious life."
"The search for truth man must weigh religious questions in the balance of science and reason."
I have to leave this for now and will continue to the gist of the issue of creation and such later this evening...
Alright so returning... there are in my view three aspects of the process in the Baha'i Writings...
We acknowledge
"creation" as an ongoing process;
"All originated from God and returneth unto Him: verily He is the Source of creation and the Goal of the worlds." (Abdu'l-Baha, A Traveller's Narrative, p. 83)
What is the nature of the connection between God and the creature -- that is to say, between the Independent, the Most High, and the other beings?
Answer. --
The connection between God and the creatures is that of the creator to the creation; it is like the connection between the sun and the dark bodies of contingent beings, and is the connection between the maker and the things that he has made. The sun in its own essence is independent of the bodies which it lights, for its light is in itself and is free and independent of the terrestrial globe; so the earth is under the influence of the sun and receives its light, whereas the sun and its rays are entirely independent of the earth. But if there were no sun, the earth and all earthly beings could not exist. The dependence of the creatures upon God is a dependence of emanation -- that is to say, creatures emanate from God; they do not manifest Him.
(Abdu'l-Baha, Some Answered Questions, p. 202)
The universe has no beginning or end:
"...it is certain that this world of existence, this endless universe, has neither beginning nor end. Yes, it may be that one of the parts of the universe, one of the globes, for example, may come into existence, or may be disintegrated, but the other endless globes are still existing; the universe would not be disordered nor destroyed."
(Abdu'l-Baha, Some Answered Questions, p. 180)
Evolution is also part of the process:
"....as man in the womb of the mother passes from form to form, from shape to shape, changes and develops, and is still the human species from the beginning of the embryonic period -- in the same way man, from the beginning of his existence in the matrix of the world, is also a distinct species -- that is, man -- and has gradually evolved from one form to another..."
(Abdu'l-Baha, Some Answered Questions, p. 192)
Finally and in closing there's an excellent article on wikipedia on the subject:
