In The Priest in Union with Christ, the famous Thomistic theologian Fr. Garrigou-Lagrange, O.P. expounds in a disciplined manner upon the specific holiness of the priesthood and the supernatural fruitfulness of the priestly apostolate.
Steeped in Sacred Scripture, St. Thomas Aquinas and other traditional Catholic sources, the author presents the classic Catholic traditions on the priestly vocation—traditions which many seminarians and young priests today may have never even heard of. He begins by explaining the character and the specific sacramental grace of Holy Orders, as well as the central sacerdotal work: to offer the Holy Sacrifice of the Mass. From this foundation he proceeds to the interior life of the priest, and then to the priest's apostolate as confessor; as preacher and as spiritual director, keeping constantly focused on the great twofold goal of every priest's life: the glory of God and the salvation of souls. For without this constant “bias toward eternity” in all he does, the priest is fundamentally off course.
