Complete Gender Equality before God

 For you did not receive a spirit of slavery to fall back into fear, but you have received a spirit of adoption. When we cry, “Abba! Father!” Ro 8:15 NRSV

If as an adult man or woman you are obliged to always fulfil the expectations of your parents, your spouse or your pastor, you are enslaved, because you are not free to follow the direct guidance of the Holy Spirit.

In the Roman Empire, sons and daughters were by no means equal. The son was the heir of the father. The wife always had to obey her father or husband.

In Romans 8, Paul says all believers are adopted as children and heirs of God. In Roman law, an adopted son became the heir of the adopting father, equal in status with a natural born son.

Only sons were heirs, not daughters

In Romans and Galatians, Paul taught that as Christians we are all have the status of adopted sons and heirs, not only men but also women. It means that she is equal with the brothers in the faith. 

This is not only an indication of the value of her soul, but also a clear teaching that she is equal in everything, because in Roman law, sonship was primarily a legal status.

and if children, then heirs, heirs of God and joint heirs with Christ—if, in fact, we suffer with him so that we may also be glorified with him. Ro 8:17 NRSV

Being an heir does not only mean being loved and valued, but also having the legal standing of an heir, which means complete gender equality in every sense of the word.

But when the fullness of the time came, God sent forth His Son, born of a woman, born under the Law,

so that He might redeem those who were under the Law, that we might receive the adoption as sons. 

Because you are sons, God has sent forth the Spirit of His Son into our hearts, crying, “Abba! Father!”
 
Therefore you are no longer a slave, but a son; and if a son, then an heir through God. Ga 4:4–7 NASB95

Doctrines of gender based Christian hierarchy are mainly based on dubiously interpreted proof texts, verses taken out of context.
