When Pope Benedict XVI inaugurated the Year for Priests in 2009, he did so in conjunction with celebrating the 150th anniversary of the death of John Vianney, the patron saint of all parish priests. Benedict's purpose for that special year is the same purpose of this book of homilies—to deepen the commitment of all priests to interior renewal for the sake of a stronger and more incisive witness to the Gospel in today's world. As St. John Vianney would often say, "The priesthood is the love of the heart of Jesus." This touching expression makes us reflect on the immense gift that priests represent, not only for the Church but for all mankind. Contemporary men and women need priests to be distinguished by their determined witness to Christ.  These homilies are meant to illuminate and to inspire priests to renew their commitment to "teaching and learning the love of God". The homilies cover a wide variety of important topics on the priesthood, all deeply rooted in Scripture, including acting in , becoming an offering with Christ for the salvation of mankind, being there for God's mercy, and witnessing Christian joy.
