Magnus—the Great—is a title perfectly befitting Pope Gregory I, lauded by Pope Benedict XVI as “one of the greatest Fathers in the history of the Church.” Dividing his guidance for pastors into four parts, Gregory explains the nature of the pastoral vocation; the essential qualities of the pastor; the true scope of pastoral ministry; and the necessity, in pastoral ministry, of unity with Jesus the High Priest in coming to serve, not to be served. The Book of Pastoral Care, whose effects have been felt and borne fruit in every century since its original appearance, is reinvigorated in this newly edited edition and remains a source of equal edification and delight for all the faithful in the present age.
