Editae Saepe §3

³ We have already pointed to how Divine Providence was perfectly realized in the lives of those three great doctors and pastors of the Church, Gregory the Great, John Chrysostom and Anselm of Aosta. Although they were separated by centuries, the Church was beset by many serious dangers in each of their respective ages. In recent years We celebrated all of their solemn centenaries. In a very special way, however, we commemorated Saint Gregory the Great in the encyclical of March 12, 1904, and Saint Anselm in the encyclical of April 21, 1909. In these documents We treated those points of Christian doctrine and morals found in the example and teaching of these saints which We thought were best suited to our times.
