After being called to the Cardinalate by Pope Clement VIII, Robert Bellarmine, one of only two Jesuit Doctors of the Church, found need for a reprieve from what were often tiresome temporal duties. Therefore, to exhaust his intellectual and devotional energies in writing, he prepared for posterity his very own commentary on each of the Psalms. Most of the Psalms of David, he said, read like a compendium of the whole of the Old Testament, a summation in poetic capsule. Others (Ps. 2, 21, 44 & 60) speak so clearly of Christ that they seem rather to belong to the Gospels. Yet, it is not the royal prophet, rather, it is the Holy Ghost, the true Author, Who desires to pluck this ten-stringed instrument of beauty called the Psaltery and bring our hearts to tears or jubilation as we sing praise to the Most High. This is a huge book of nearly four hundred pages, a spiritual goldmine.
