>>I sees no reference to “fellow servants”<<
If you read the rest of Matthew 18 Jesus teaches of the servants. After all the entire chapter starts with the question, “Who is the greatest in the kingdom of heaven?”
There are those who are chosen to lead the church, not rule over it. That is Jesus place, not any man.
So which is it chosen to lead or serve? Lead implies leadership. To serve implies subservience. Why is it not both/and?
The pope and the rest of the hierarchy do not rule, they serve under the inspiration of the Holy Spirit.
The pope is called the “Servant of the servants of God.”
If you read the rest of Matthew 18 Jesus teaches of the servants. After all the entire chapter starts with the question, “Who is the greatest in the kingdom of heaven?”
The only accurate sentence in that is that the chapter stars with “Who is the greatest in the kingdom of heaven?”
I have read it more than once and the only servant is the one who refused to forgive the debt of another.
As for who is the greatest, Jesus says the one who has become like a child, the one who is humble like the child.
What is it that makes the child humble?
How humble is it to believe in one’s own infallibility in determining and interpreting Scripture?
