The Bible is full of teaching on various topics and instructions on how Christ intends for his church to operate.
One such teaching is the fact that He instructed that no one should be called rabbi, father, etc.
In Matthew 23:8-10, He is speaking to His disciples and the crowd that has gathered, informing them not to follow the ways of the Pharisees and how they do things to be “seen by men”.
Outside of the specific terms being used (there are entire religions built upon using these terms Christ speaks against), there is also an underlying message He is presenting.
Do not put yourself, or allow anyone to be put in a position of authority in your life that only belongs to God!
We have one Teacher, we have one Father, we have one Instructor…God
