Illuminating the complexity of the human condition as well as the phenomenon in which we are all limited by (and products of) our times, is St. Bernard of Clairvaux. Bernard is well known as a Saint of the Catholic Church, a primary founder of the reforming Cistercian Order, and now even a Doctor of the Church, Bernard is a more complicated person.
On this day, March 31, 2015, Bernard of Clairvaux gave what is now known as his famous sermon in a field at Vézelay, urging the necessity of a Second Crusade. As a result of the sermon, Louis VII of France endorsed the Second Crusade and thus other monarchs supported the crusade as well. In addition to encouraging religious warfare, the crusades led to the sacking of Lisbon by English knights as well as countless battles in the Holy Land.
In his Book of Consideration, Bernard explains how the sins of the crusaders were the cause of their misfortune and failures.
