This book is an in-depth theological study of the Four Gospels (the Gospel of John) and the Johannine epistles. The author presents an original analysis based on years of reflection. The book is structured into three parts: (a) the Gospel Formation section, which discusses the relationship of the Gospel of John to the Johannine epistles, internal parallelism, the extensive editing process, and the literary purpose of the Gospels; (b) the Gospel Message section, which presents the message of the Gospel and the First Epistle in the form of 'What Jesus Gave' and 'What Jesus Took', followed by John's Christology; and (c) the Evangelist section, which interprets the evidence for the Gospel's authorship, background, and formation, particularly that the Gospel of John was written by John Mark, also known as the Beloved Disciple. This book has been described as a challenging and eloquent work, suitable for serious study of Johannine theology and providing original insights into the origins and theology of the Gospel of John.
