What about our biological fathers?
Hi Nakus, I hope you like this Worthy site, I do and welcome (lots of good folks here).
Umm..,all scripture has a subject that needs to be followed, Christ is talking to disciples and the multitudes and it's the scribes & pharisees (diffrent sects that He knows to be wrong in their teachings) that are false teachers of GOD's will and Word. The verses leading to your question (9) gives you the answer you're looking for that is: Who is your Master, GOD of course, so He's not talking about biological fathers.
Edited to say that I liked Openly Curious's (good one) post: #3
