This online independent study course will be an excursion into the least known, least popular, yet, most underrated of the four Gospels--inspired by God and written by the man who was Peter's secretary. Mark affords us an indispensable look into Jesus Christ and the true meaning of Christian discipleship. The content will explore many puzzles of this Gospel, including the reasons why Mark has so often been neglected in the history of the Church, and why Mark, despite his relative neglect in the past, is essential in his witness to the truth of Jesus Christ and the historical memory of the Lord's life and ministry. Furthermore, participants who complete the seminar should be able to give reasons why Mark is an outstanding catechetical tool for explaining the mystery of Christian discipleship.
