You are not reading the teachings of the Bible. This is a violation of the fifth commandment, "Honour thy father and thy mother: that thy days may be long upon the land which the LORD thy God giveth thee.Exo 20:12 The Bible does not command us to 'disown' our parents. It commands us not to love the world,I John 2:15 but to love God.Deut 6:5 Also we are told that, "Have ye not read...For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?Matt 19:5
Exodus 20:12 - Honour thy father and thy mother: that thy days may be long upon the land which the LORD thy God giveth thee.
1 John 2:15 - Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him.
Deuteronomy 6:5 - And thou shalf love the LORD thy God with all thine heart, and with all thy soul, and with all thy might.
Matthew 19:4-6 - 4 And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female, 5 And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh? 6 Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.
If, as you say, no Christian can call any earhtly man “father”, then no Christian can obey the 10 commandments, as you have also pointed out.
Looks like the bible has got you trapped in a bit of a conundrum. I am so glad I have the Church to help me understand these scriptures as they have been understood for over 2000 years.
