St. Bernard of Clairvaux has numerous titles: preacher, miracle worker, advisor of popes, defender of faith, arbitrator.. and many others. One of the most distinguishable 12th century historical figures, St. Bernard was not only Holy but also known to be a very intelligent theologian. Proclaimed as Doctor of the Church in 1830, Pope Pius XII said in his encyclical Doctor Mellifluus about St. Bernard: “the last of the Fathers, but certainly not inferior to the earlier ones.” St. Bernard’s feast day is August 20th.
