Theophylact of Ohrid
Catena Aurea · Lukasevangelium 10
And, behold, a certain Lawyer stood up, and tempted him, saying, Master, what shall I do to inherit eternal life? He said unto him, What is written in the law? how readest thou? And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself. And he said unto him, Thou hast answered right: this do, and thou shalt live.
We must hereby understand that it becomes us to submit every power of the soul to the divine love, and that resolutely, not slackly. Hence it is added, And with all thy strength.
