But when He emptied Himself, taking the form of a servant (Phil 2:7), He did not lay aside what He had. He took what He did not have.
Going to crucifixion, He was stripped of His garments. When He died, He was wrapped in linens (see Jn 19:23-24, 40).
All His suffering is for our cleansing.
As He prepared to endure the end of His sufferings, He here sent ahead His service not only to those for whom He was going to die, but also to him who was ready to betray Him to death.
Behold how great is the benefit of human humility, since even the divine Majesty demonstrates it by His example.
Proud man would have perished forever, had the humble God not found him.
For the Son of Man came to seek and to save the lost (Lk 19:10).
Since man perished by imitating the pride of the deceiver, now that he has been found, let him imitate the humility of the Redeemer.
And behold, knowing this, He rose from supper, laid aside His outer garments, and, taking a towel, girded Himself.
Then He poured water into a basin and began to wash the disciples' feet, and to wipe them with the towel with which He was girded.
Beloved, we must listen attentively to what the Evangelist says.
When he was about to speak of the Lord's great humility, he first wished to speak of His greatness.
To this belongs what he said: knowing that the Father had given all things into His hands, and that He had come from God and was going to God.
And so, when the Father had given all things into His hands, He washed not the hands, but the feet of the disciples.
Although He knew that He had come from God and was going to God, He performed the duties not of the Lord God, but of a manservant.
To this also belongs his wish to speak at once of His betrayer, who had already come to the supper as such and was not hidden from Him.
Thus to the greatness of His humility was added this also: He did not think it unworthy of Himself to wash even the feet of him in whose hands He already foresaw the crime.
What is astonishing if He rose from supper and laid aside His garments, who, being in the form of God, emptied Himself?
What is astonishing if He girded Himself with a towel, who, taking the form of a servant, was found in appearance as a man? (cf. Phil 2:6-7).
What is astonishing if He poured water into a basin to wash the disciples' feet, who poured His blood into the earth to wash away the filth of transgressions?
What is astonishing if He wiped with the towel with which He was girded the feet that He had washed?
He, by the flesh in which He was clothed, left footprints for the evangelists.
Although, to gird Himself with a towel, He laid aside the garments He had, yet, to take the form of a servant when He emptied Himself, He did not put away what He had. That is, He did not abandon the Godhead.
He took what He did not have.
When He was crucified, He was indeed stripped of His garments. When dead, He was wrapped in linens.
All His Passion is our cleansing.
And so, as He prepared to suffer death, He showed submission not only toward those for whose sake He intended to accept death, but also toward him who had resolved to betray Him to death.
Surely the benefit of human humility was so great that even the divine Majesty entrusted it by His own example.
For man, puffed up with pride, would have perished forever, had the humbled God not found him.
For the Son of Man came to seek and to save the lost (Lk 19:10).
It perished by imitating the pride of the deceiver. Therefore now, having been sought out, let it imitate the humility of the Redeemer.
