Did Les think modern technological society was returning to the idolatry of Romans 1?
Yes. Modern highly technological, intellectual society is returning to the same idolatry described in Romans 1, exchanging the glory of the uncorruptible God for created things. The New Age movement is cited as evidence of this return to Oriental idol worship in subtle forms.
Les teaches that Romans 1 describes a reversed chronology from creation: idolaters first make images of man, then birds, four-footed beasts, and reptiles, descending to the lowest creatures. He illustrates this with Egypt under the Pharaohs, where frogs, flies, and the Nile were gods, and God's plagues proved those gods were nothing. Les then notes that in 1995 an intellectual, highly technologized man with all his technology is coming back to the same place. He identifies the New Age movement as coming under Oriental idol worship in subtle terms.
