Egalitarian claim: kephale means 'source' only, not authority; complementarian claim: it includes authority

Egalitarians claim that when the Bible says husband is head, the word only means 'source' (as in Adam being the source of Eve) and implies nothing about authority. Complementarians say it does imply authority. Complementarians do not deny it can mean source — they assert it includes authority. The real debate is whether authority is included.
