First, I'd suggest you to take some classes on writing and syntax, your posts are barely readable and understandable.
Second, the old testament is the foundation of the new one so its core tenants are still considered valid by all Christian denominations, some even recognizing it more authority in respect to the new testament.
Third, a father should be obeyed AS LONG AS he is a reasonable and caring father. An abusive or violent parent should not be obeyed just like a tyrannical or undemocratic ruler shouldn't, expecially if they ask for something causing stress or harm to his children/subjects.
Fourth, a child would also not exist without his mother but in your Christian mindset this is never taken into account.
