It would be equally dishonest in the reverse case -- if evolutionary biology tried to elbow its way into the pulpit while falsely pretending to be revealed religion.
This statement actually touches on the heart of the argument.
Evolutionary biology without faith in God has created a pulpit in the classroom forming its religion worshipping rationalism and the Creation. Scripture is God's Word revealed to man, but religion is not a revelation, rather it is a system of worship. By excluding God or faith in Him from evolutionary theory or the classroom, the state is establishing a religion.
