Darkness Visible: A Christian Appraisal of Freemasonry by Walton Hannah

As a practising Christian, is Freemasonry compatible with one's duty to Jesus Christ? That is the question which the Rev. Walton Hannah, then a Church of England clergyman (and subsequently a Catholic priest), set himself to answer with the publication of Darkness Visible in 1952. Darkness Visible contains the entire and authentic text of the Masonic ritual of the first three degrees and of the Royal Arch. Hannah wrote this book to substantiate his conviction that for a quasi-religious organisation such as Freemasonry to offer prayers and worship to God but exclude the name of Jesus Christ demonstrates its incompatibility with Christianity.
