Then why have you posted this in the Women's Ordination section of this forum?
Every Adventist studying these things knows how crucial finding at least something from the Bible that might hint at an ordained woman, or even a woman in leadership, would be. That is why people endeavor to make something of where the mere mention of a woman exists.
Of course, what you have said is a lie. In the Bible, it is not about ordination AT ALL. And here on this forum, that is exactly what it is all about.
If "laboring together" means all of the co-laborers are "leaders," you may need to start writing your own dictionaries to establish the fact.
Headship is Biblical, therefore it is not a heresy. God never once put a woman into a position of authority over His people. Jesus selected and ordained no female disciples. In order to endorse women's ordination, you will need good explanations for these facts, and for why they should not be used as examples of today's gospel order. In the end, you will be grasping for support from all of the world's authors, and rejecting Ellen White, just as the author of the article in the OP here has had to do.
What substance?
