St. John Climacus March 30

While still young, St. John had achieved such a reputation for learning that he was called the Scholastic. He gave up what promised to be a brilliant career and retired to a solitude on Mt. Sinai. Other young men came to him, for whom he founded a monastery and wrote Climax, or Ladder of Perfection.

He that hath clean hands and a pure heart, who hath not lifted up his soul unto vanity, nor sworn deceitfully unto his neighbor, he shall receive a blessing from the Lord. — Matins, Psalm 23

The Imitation of Christ
I am He that in an instant elevateth the humble mind to comprehend more reasons of the eternal truth than if anyone had studied ten years in the schools.
This is the fourth saint in succession by the name of John. He had a very, very bright mind and a splendid opportunity to make a name for himself, but he left all to become a monk in the desert; he was sixteen at the time he entered the desert.
The monks said of St. John that there never was a more docile monk than he. Sometimes when students are especially bright, they get the mistaken notion that they know more than their parents. That very fact betrays ignorance.
Fools rush in where angels fear to tread.
