There is the enormous corpus of Islamic law that is very rich. However, law is one rational exercise of reason. Philosophy is very different. Philosophy wants to try to understand everything. It is a better dialogue partner with faith than law.

That question in marriage is mutual submission, really - the next verse goes on: "husbands love your wife as Christ loves the Church."

God's is the causality at the level of our being, and therefore the roots of our freedom. Ours in causality is determinative of what kind of being we're going to be through our free choices, what kind of action we are going to do through our decisions.

Love isn't blind. Love is reasonable. God is pure love, but He is also pure reason. If you separate reason from faith you'll end in violence. Either way, if you have a purely rationalistic scheme that is atheistic, for instance Communism was for social justice. Fascism was for the nation-state, which isn't automatically a bad thing.

If you, however, separate reason and faith so that it's purely a rationalistic scheme, it will end in violence. If a pure faith scheme - sometimes called the fundamentalist scheme in modern parlance - you'll end in violence too.

Christ didn't leave us a book of instructions; He left us a body, a family - a Church. If it were perfectly clear, there wouldn't be any freedom.

From a Christian perspective, the answer to all of that is not power, as it is in the modern perspective. It's love. It's self-sacrifice. That's what love is all about. The marriage ceremony says it very well: sacrifice is difficult, but love can make it a joy.
