Supernatural Religion

Supernatural Religion... excited much interest by the outspoken criticism pervading it. The learned work furnishes efficient aid to rational inquiry, and deserves to be studied by all lovers of free investigation. The assaults which were made upon minor details leave its main positions unharmed."[1]

Cassels is renowned as the author of the anonymous work that appeared in 1874 under the title Supernatural Religion: An Inquiry into the Reality of Divine Revelation. The work at once attracted attention, and it resulted in much speculation about the real author. But no one ever admitted openly of its writing. In a reply to this book many articles and books were written. The most famous were essays written by Bishop J. B. Lightfoot, and printed later as a book. As a result a third volume was added to Supernatural Religion, and a revised edition was published in 1879. Replies to Bishop Lightfoot and other critics were made anonymously, appearing in magazine articles and as footnotes or prefaces to later editions of Supernatural Religion. These replies were also printed as a book.

Speculation that Cassels is the author surfaced in 1895 after his publication of a series of theological articles. Cassels however never publicly acknowledged his authorship of Supernatural Religion. Not much is known about his private life or how he became an early Christianity expert. He wrote poetry and was an art collector. Never married, he died in London on 10 June 1907. Wikipedia
