In the book of Genesis God made woman from the rib of man which may have given men authority over women. In the later chapters of Genesis when Eve took the apple of knowledge there is evidence that God punished man and woman for the disobedience. One may even argue that man was punished more severely by God (in reading God's response to both man and woman). A later chapter of Genesis (Chapt 5) shares another story of creation whereby Man (Hebrew) or Adam (Greek) is deemed to be both male and female. This may be a more imminent account of the placement of male and female genders in God's world.
An equal rights amendment would be a force in our society that diminishes the ability of male authority to over assert its powers on the opposite gender. Accounts today may indicate a need for this type of right sanctioned by our government and for the world in order to create a good balance again. Such an amendment likely would not change the original placement of the male gender in God's world but it would manage the forces that are being utilized abusively today within the structures that were created.
