Hi
Eph.6:1-4 are clear examples that our biological fathers may be called "father".
God bless,
duval
Good answer Duval. I think that Brother David is thinking about:
Matthew 23:9-10 KJV And call no man your father upon the earth: for one is your Father, which is in heaven. 10 Neither be ye called masters: for one is your Master, even Christ.
Matthew 23 here is talking about a spiritual sense - replacing our Heavenly Father with a man. This would be a troubling question for some religions that refer to their spiritual leaders as Father. Duval, you chose an excellent portion of Scripture to illustrate the difference.
Love In Christ,
Tom
