This book explains in detail the votaries of the ancient Astral worship divided into two distinct classes, the Esoterics, or Gnostics; and the Exoterics, or Agnostics; the former comprising those who knew that the Gods were mythical and the scriptures allegorical; and the latter, those who were taught that the Gods were real, and the scriptures historical; or, in other words, it was philosophy for the cultured few, and religion for the ignorant multitude. The initiates into the secrets of these two systems recognized them as the two Gospels; and Paul must have had reference to them in his Epistle to the Galatians ii., 2, where he distinguishes the Gospel which he preached on ordinary occasions from that Gospel which he preached ‘privately to them which were of reputation.’
