One very important adjectiive - "Holy". Why would you call only one man Holy when we are all called to be holy. Jesus said, your leaders wll not be like the Gentiles that they rule over you - they will be your servants and the Pope rules over the Catholic church very much as one of those earhly leaders.
You set him aside (which is what "holiness" means) but you do so in ascendancy. He's not only set aside from the world, he's set aside from the church and he's set over the church in strict disobedience to Christ.
Further, do you kiss each other's hands? If you honored each other as you honor the Pope I would certainly not be tempted to see any particular idolatry there. Unfortunately that's not what I see nor is it what the rest of humanity sees.
The Lord says "do not" and the ECFs and popes say "do" - the essence of idolatry is placing something else before the Lord.
If the essence of Rome is idolatry and, particularly, emperor worship, then it never fell.
