Call no one "father", in the spiritual sense. Your spiritual Father is the Father in Heaven - the Heaven of Heavens, Paradise.
It is very dangerous to call a fellow human being your "father in the Lord", "Papa", "Mama", "spiritual father", etc. When you do so, you may end up worshipping them and you may not be very conscious of this happening. A "personality cult" may develop around the person. Many people may start bowing down to and worshipping him or her - unconsciously. As a human being, you have a "WORSHIP CIRCUIT" built into you. You are "fearfully and wonderfully made" - you are intricate, delicate, superbly special and wonderful. There's a worship circuitry that connects you to the Paradise Father - directly!
If you are not careful, you may find yourself channelling that built-in worship circuitry to that man or woman you call your spiritual father/mother, Papa/Mama. That individual may end up taking the place of God in your life. That's a curse! That's very, very dangerous! Your eternity may be at stake! Your life on Earth may become messed up! This is no joke at all, beloved...
We are all brothers and sisters - children of God. Some of us are lost like the Prodigal Son. Some of us are saved - salvaged sons and daughters of the Heavenly Father. You should love and honor those who teach you TRUTH but you must not worship them. Don't call them "father" or "mother". They are your brothers and sisters. Yes, they may be more spiritually matured. But this doesn't make them better than you in the sight of God. Learn to love everyone, including your enemies. Fear no one. Bow down to no one. God bless and keep you! Amen.
"And call not [any one] your father upon the earth; for one is your Father, he who is in the heavens." - Jesus, Matthew 23:9 Darby Bible Translation
“While you should honor your rulers and reverence your teachers, you should call no man Father in the spiritual sense, for there is one who is your Father, even God. Neither should you seek to lord it over your brethren in the kingdom. Remember, I have taught you that he who would be greatest among you should become the server of all. If you presume to exalt yourselves before God, you will certainly be humbled; but whoso truly humbles himself will surely be exalted. Seek in your daily lives, not self-glorification, but the glory of God. Intelligently subordinate your own wills to the will of the Father in heaven." - Jesus, The Urantia Book 175:1.10
