“…be not ye called Rabbi: for one is you Master, even Christ; and all ye are brethren.

And call no man your father upon the earth: for one is your Father, which is in heaven.

Neither be ye called masters: for one is you Master, even Christ.

But he that is greatest among you shall be your servant.

And whosoever shall exalt himself shall be humbled; and he that shall humble himself shall be exalted.” (Matthew 23 8-12) (The Holy Bible)
