Thomas Merton presented numerous sets of conferences during his decade (1955-1965) as novice master at the Cistercian Abbey of Gethsemani. The two courses included in this volume - a thorough examination of the book of Genesis that began in mid-1956 and concluded on the Feast of Pentecost in 1957, and a series of classes on the book of Exodus from 1957 and 1958 - are here presented for the first time in a critical edition accompanied by extensive annotation and a comprehensive introduction. These courses comprise the only major surviving teaching notes on particular books of Scripture dating from the years when Merton was in charge of the novitiate. They provide direct access to his views on the intellectual and spiritual contexts in which they should be understood. As biblical scholar Pauline Viviano writes in her preface, 'this edition of Thomas Merton's class notes brings us into the workings of a great spiritual leader's mind as he reflects upon Scripture. ... all who are on a spiritual journey can gain from his insights and the lessons he draws.'
