George Leo Haydock

Whilst the Jews proceeded no farther than to admire the wisdom of our Saviour, when they could easily have seen that what he taught he knew by the power of God, Christ himself reveals to them the source of his wisdom, saying: My doctrine is not mine, but his that sent me. (St. Chrysostom, hom. xlviii. in Joan.) — St. Thomas Aquinas, the great doctor of the schools, and styled the angelic doctor, informs us that in all the scriptural difficulties he met with, he uniformly had recourse to prayer, and that he acquired greater light and knowledge at the foot of his crucifix than from any books or masters.
