Not correct.
Dr. Dini, himself a Christian, did not require a disavowal of religious beliefs in a Creator; just a scientific answer to the question: "How do you think the human species originated?".
As a biology professor, clearly he was looking for a solid understand of evolution on the part of the student.
There were 38 other professors whose classes Micah Spradling could have attended and from whom he could have requested recommendations.
Amazingly Spradling managed to sign up for a class from the one professor that (for 10 years) publicly required an acceptance of evolution for recommendation.
Like the Scopes trial it was a staged provocation. Micah Spradling never sat in any of Dr. Dini's lectures. Once he made his complaint, he dropped the course and transfered to Lubbock Christian.
Why would he use the phrase, "truthfully and forthrightly affirm"???? He could have simply state the student will need to be able to provide a scientific answer. When he uses the phrase, "truthfully and forthrightly affirm" he is going beyond asking for a simple answer. He is asking for an oath.
