This years Sperry Symposium volume sheds important light on the mission of the man whom Jesus himself referred to as “the rock.” As a sometimes fallible but nonetheless earnest disciple, Peter is an important example of grace, transformation, service, and power. Essays in this collection treat his cultural background and context, his role in the apostolic church, many of his noted teachings, and his important legacy in early Christianity and the Restoration. But above all, Peter is revealed as one who, through the Atonement and the endowment of the Spirit, overcame his own weaknesses to become one of the greatest, and most powerful, witnesses of the divinity, mission, and resurrection of Jesus Christ.
