What is your exact objection to those pictures?
I did, which is why I am asking for greater specificity.
Jesus warned His disciples that the church is not supposed to have "rulers," lords, or "high officials" over it. Jesus calls himself a "servant" and says that anyone would be prominent in the church must be the same, a servant, not a "ruler."
A pope in fancy robes and whatever you call that thing on his head being carried through a crowd certainly looks more like a monarch than a servant.
25 Jesus called them together and said, “You know that the rulers of the Gentiles lord it over them, and their high officials exercise authority over them.
26 Not so with you. Instead, whoever wants to become great among you must be your servant,
27 and whoever wants to be first must be your slave—
28 just as the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many.”
--Matthew 20:25-28 NIV
42 Jesus called them together and said, “You know that those who are regarded as rulers of the Gentiles lord it over them, and their high officials exercise authority over them.
43 Not so with you. Instead, whoever wants to become great among you must be your servant,
44 and whoever wants to be first must be slave of all.
45 For even the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many.”
--Mark 10: 42-45 NIV
25 Jesus said to them, “The kings of the Gentiles lord it over them; and those who exercise authority over them call themselves Benefactors.
26 But you are not to be like that. Instead, the greatest among you should be like the youngest, and the one who rules like the one who serves.
27 For who is greater, the one who is at the table or the one who serves? Is it not the one who is at the table? But I am among you as one who serves.
-- Luke 22:25-27 NIV
This point is found in all three synoptic Gospels.
