Bruce Ware state this myth thusly:
“Man is the image of God directly, woman is the image of God only through the man… Because man was created by God in His image first, man alone was created in a direct and unmediated fashion as the image of God, manifesting then the glory of God in man, that is male man… If male headship is rooted in the image of God itself, then it isn’t just a functional distinction of how we work out. It really does mean we are made in a different way.
It may be best to understand the original creation of male and female as one in which the male was made in the image of God in a direct, unmediated and unilateral fashion, while the female was made image of God through the man and hence in a indirect, mediated and derivative fashion.” – Bruce Ware
Firstly, this is not in the Bible. Here is what the Bible directly say:
27 So God created mankind in his own image, in the image of God he created them; male and female he created them.
Yes, Adam was made first, and then Eve from Him. But being made first does not translate to being made directly in God’s image, while the second is less so.
Secondly, it is not a logical conclusion: Here are a few examples:
> A baker bakes some cookies. He makes dough first, and then he bakes (derives) the cookies from the dough. Could we say that dough is more in the image of what the cook wanted to make, and baked cookies less so? Not at all.
> A writer writes a story in which one of the characters Anne-Marie Roestoff, pretty much reflect her own way of thinking. She later writes another book featuring Mrs. Roestoff, building onto what her readers already know about the woman from the first book. Could you say that the first book’s Anne-Marie Roestoff is more like the writer, while the second is only like her in so much as it derives from the first? Of course not. The writer could put the same amount of herself, or more, into how the character acts in the second book.
Thirdly, it leads to unscriptural practices and messages, because it tells women their identity is found in man, not God.
