St. Albert the Great (1206-1280)
Albert was a Dominican philosopher, theologian, and scientist. He taught at Cologne and Paris, where he had Thomas Aquinas among his pupils, and compiled an encyclopedia of the learning of his day. His study of the natural sciences was far ahead of his time.

Reflections from the Saints

It is by the path of love, which is charity, that God draws near to man, and man to God. But where charity is not found, God cannot dwell. If, then, we possess charity, we possess God, for "God is Charity."
– St. Albert the Great
