It was a literal command.....<quoted text>
Jesus also told us to pluck out our eyes if it causes us to sin. I'm surprised you can see your keyboard.
'call no man father' wasn't a literal command. It was in reference to the scribes of the day who enjoyed and took advantage of the perks they gave themselves for being Rabbis. They were hypocrites. Christ was using something called 'hyperbole' which is an exaggeration or 'making an extravagant statement to get your point across.
When the Apostle Paul called Timothy 'my Son' you can be sure as the sky is blue, that Timothy in turn, called Paul 'father'. This is the language, guest. It would have been disrespectful for Timothy to not call Paul 'father' when Paul called him son.
The term "father" denotes authority, eminence, superiority, a right to command, and a claim to particular respect. In is in that sense it is used here. In this sense it belongs eminently to God, and it is not right to give it to men.
But....the Catholics say, "What does God know??? As a matter of fact, calling the pope Holy Father, is acknowledging his authority, eminence, his superiority, his right to command, and a claim to particular respect."
