Originally published in 1910, this book contains an exhaustive study of the use of the phrase 'Son of Man' in the Old and New Testaments. Abbott illustrates how Christian writers used the mystical trope present in many books of Jewish prophecy to convey their belief in Christ as an eschatological figure foretold by Scripture. This book will be of value to anyone with an interest in Christology and the use of this enigmatic title in Jewish and Christian theology.
