Revelation Spiritually Understood: The Glories of Christ & His Church
A Spiritual Exposition of the Book of Revelation by Charles D. Alexander is arguably his best written contribution to the Church.
It is “a powerful attack on the twin errors of Dispensationalism and Post-millennialism, and is a compulsive and compelling defence of the Amillennialist position. However it is more than a theological treatise, though it is very much that. In language reminiscent of the 19th century, it is a warm setting forth of the glories of Christ and His Church in her march through history to the consummation.”
