I suggest you are using a straw man argument here, intending by exaggeration to suggest that any criticism of any Old Testament law (such as laws regulating the use of slavery assuming that slavery was an OK by God and slave owning men), is a direct attack upon God's integrity. This seems to work well only if the assumption is made that all of OT scripture must be understood to be the actual moral precepts of Almighty God, and not a record of the legislative norms of a late Bronze Age agrarian/semi nomadic society. Set fire to that straw man and it's imagined by its artificer that what's left is a victorious fundamentalist interpretation of the Old Testament as a blueprint for the perfect, God ordained system of Law, which if imposed upon the world, (as God did upon the Israelites), would result in blissful Utopia for all the Earth and its inhabitants. But it IS only a straw man because The Law and Old Testament values, no matter how elevated by a fundamentalist belief system, to the status of "The words and Edicts of Almighty God", which such a belief system dictates, " should guide our lives and actions in every conceivable way," is incapable of ever delivering such a Utopia. The Teachings of Jesus Christ and all of His Apostles and Evangelists fully confirm that fact. When asked "“Teacher, which commandment in the law is the greatest?” He said to him, “ ‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’ This is the greatest and first commandment. And a second is like it: ‘You shall love your neighbour as yourself.’ On these two commandments hang all the law and the prophets.” Far from implying that The Old Testament Law is a comprehensive manual of perfect God given rules, ensuring a perfect society on Earth, if followed to the letter, Jesus Christ is saying that LOVE itself can only be learned and gained directly from GOD. And it is THIS alone which can discern the mind of God on how we should interact with our neighbours on Earth. Therefore a codified system of Love management through The Law is simply not available to mankind - EXCEPT through the ministry of The Holy Spirit and a God imparted - renewed heart. If this, (Christ suggested), new method of discerning the extent that Women's Ministry is allowable by God, quite apart from any Old Testament "LAW" or "Example", one simply cannot point to Old Testament LAW or example and use it as a guide to correct praxis in Christ's Church. It would be an ABUSE of Old Testament Law and New Testament "Life", to try to use it that way in support of arguments against the emancipation and elevation of our sisters in Christ to the office of the priesthood by Christ's church on Earth, directly guided by The Spirit of the God, that it's first commandment is to LOVE ONE ANOTHER. .
