“In the days of His flesh” .. so the Book of Hebrews refers to the days when, according to His human nature, Jesus did not fully use the divine attributes of the Godhead communicated to His human nature. Humiliation is a state or condition in which a person of high honor and position is in a condition of lesser honor and practice. In the Bible, Christians are enjoined to have the attitude of humbleness seen in Christ through His work of redemption;
“Let this mind be in you which was also in Christ Jesus, Who, being in the form of God, thought it not robbery to be equal with God; but made Himself of no reputation and took upon Him the form of a servant and was made in the likeness of men; and being found in fashion as a man, He humbled Himself and became obedient unto death, even the death of the cross.”
“Thought it not robbery to be equal with God,” is a peculiar expression which warrants study to grasp the impact of the reference. It was a common practice in those days that when a victorious general returned home with his army, they entered the city in triumph, as Titus did after conquering Jerusalem, displaying the spoils of battle, and making a public show of the things they had robbed and taken from the enemy. To think a thing robbery, therefore, simply means to make a public display or show of it. Many people like to show off what they are and what they have accomplished, but such was not the case with Christ. Although He truly was “equal with God,” and possessed divine majesty and power, He did not make a public show of it. Indeed, in the days of His flesh, He did not walk about constantly radiating divine glory and demanding public honor even though He was equal with God; instead, He “made Himself of no reputation.”
This section of the Catechism teaches us about the nature of Christ and His work of redemption, and also teaches an important lesson for our life. Let this mind be in you which was also in Christ Jesus. Rather than being proud and haughty, showing off before one another and comparing what we are and what we have accomplished, we are to live in humbleness of mind and conduct.
