This volume brings together twenty-two essays on the Gospel and the Epistles of John, published in the period 1980-2014. They are the fruit of a lifelong fascination with the Johannine literature, first with the Gospel, later also with the Epistles. The first twelve chapters concern themes from Johannine literature: translation, theological issues, use and significance of the Old Testament and of Jewish tradition, and introductory questions concerning John's Epistles. The next ten chapters are studies of individual passages from Gospel and Epistles, with a special interest in passages in which interpretation of Scripture figures prominently. Together, the chapters show that a Christology centering on the human being Jesus as the only revealer of God is the heart of Johannine theology, that the Jewish Scriptures are used in John's Gospel to legitimate Jesus as God's revealer, and that this Gospel is a writing that claims to constitute a new Holy Scripture.
