What I think of is that it was said in the context of Jesus telling the apostles who were arguing about which of them was the greatest, that none of them would be above the others, and how that fact falsifies the Roman Catholic sects claim that Jesus made Peter the head of Christianity and all the apostles, and then built the Roman Catholic Church on Peter, making all believers subservient to the RCC, the pope, and papal doctrines, because all subsequent popes have Peters total authority over all Christendom, via apostolic succession.
