As the author pointed out in the article, that was not the point of the original foot washing done by Jesus. The disciples, including Judas, who like many other disciples in the future, would betray Jesus, were being sent as apostles to preach the Gospel and were being reminded that they must be humble and not treat each other with arrogance, especially if they were in positions of authority. Traditionally, the rite was limited to the Pope or a bishop, who would wash the feet of members of the clergy, reflecting the symbolism of Jesus’ act.
It wasn’t an occasion for an ostentatious display of “inclusivity” or groveling with one eye on the camera, as the Pope always does.
In any case, the article has a very good explanation of how Mulsims see this latest theatrical act by His Humbleness.
I understand and agree with your point about the reason that Jesus washed the feet of the disciple.
Judas actually knew Jesus, while other disciples who betrayed Jesus did not personally know Jesus. Just as the Lord told Thomas, you believe because you have seen, blessed are those who believe and have not seen.
I strongly agree that this pope is using these occasions to grandstand in front of the camera and the world. He receives his accolades but he will have to face Christ with his actions. I do not think the pope will receive accolades from the judge.
