Saint Albert the Great
He was the teacher of St. Thomas Aquinas, and- we believe- is now an intercessor for all students.
The great discerner of souls does not belie himself here. More than once his vast experience of life, his charity in judgment, his just and wise weighing of all the circumstances, manifest themselves. This is especially the case when Albert, as for instance in his teaching on anger, or on the spiritual works of mercy, descends to the particular and gives advice on the proper ordering of life, for then he reveals a unique greatness, a rare combination of high scientific training and a practical wisdom born of his own experience of life.... We can then catch a glimpse of his own soul, as in moving speech his loving heart sings the canticle of God.
