Mark: The Sorrowful Gospel: An Introduction to the Second Gospel by John F. O’Grady (1981) is a theological introduction that interprets the Gospel of Mark as a Gospel that highlights the suffering dimension of Jesus’ life and work. The author emphasizes that Mark’s Gospel portrays Jesus as the Messiah who must suffer, and that this path of suffering also becomes a pattern for the disciples. The theme of sorrow emerges from the disciples’ misunderstanding, rejection by society, and culminates in Jesus’ passion and death. Through this approach, the author demonstrates that suffering is not a failure, but rather a necessary part of the plan of salvation and the process of maturing faith. Overall, this book invites readers to understand Mark’s Gospel as a call to faithfully follow Christ, even amidst hardship and suffering.
