practice

By this union of the Creator with the creature the Highest was united with the lowest. Jesus Christ summed up all His Heavenly doctrine in humility, and before teaching it, it was His will to practice it perfectly Himself. As St. Augustine says: "He was unwilling to teach what He Himself was not, He was unwilling to command what He Himself did not practice." [Lib. de sancta virginit. c. xxxvi]
