From the young St. Francis de Sales's heroic efforts to bring Calvinists back to the Faith comes this succinct, eloquent defense of the age-old Catholic practice of making the Sign of the Cross, which 16th-century Calvinists denounced as a Popish invention and many Protestants scorn even today.

Embodying the zeal of youth and the wisdom of age, this gentle jewel of Catholic apologetics traces the origins of the Sign of the Cross back to the Fathers of the Church, to the Apostles before them, and finally to our Lord Himself.

Along with St. Francis's other lucid explanations of our Catholic Faith and his undaunted love even for those who hated him, this modest book helped restore to their native Catholic faith tens of thousands of heretics who not long before were intent on killing him.

As they did for the Calvinists in St. Francis's day, so in our day these words will bring you a better understanding and a renewed love the Sign of the Cross, that brief and lively exterior prayer by which, from time immemorial, God has been invoked by serious Christians before all of their endeavors.
