This book presents an integral approach to formation during the vocational synthesis stage, weaving together the human, spiritual, intellectual, and pastoral dimensions of priestly preparation. It is responsive to the Church's vision articulated in Pastores Dabo Vobis, Ratio Fundamentalis, and the Program of Priestly Formation (6th edition), offering formators a comprehensive framework for accompanying transitional deacons in their final preparation for priesthood. By providing formators with both a synthetic vision of integral formation and practical tools for implementation, it enables mentors to accompany transitional deacons through the vital process of vocational synthesis, helping them integrate their years of formation into a coherent priestly identity. May this work be for God's glory and the good of His devoted servants.
