Sue, thankyou for your questions. Let me respond the best i can. I do believe the meaning of kephale in this text is best understood authoritatively, but even if one takes the meaning of ‘source’ it should not cancel out the male headship- hence what i said on which you quoted me.
Now regarding Chapter 7. Paul is indeed portraying a mutuality of respect for each others body in sexual union. However the context here is not the same- it is about propriety in worship.
The reason i see it as husband/wife is because i think it better fits the context of his argument. The ‘covering’ was a sign of a marriage in Corinth and it seems best to apply this here. But that said there are many great minds who see it differently- for example F.F Bruce.

Regarding single women and how this applied to them is indeed a valid argument. But we need to remember the ‘norm’ was to be married, and since the issue is again the ‘covering’ it is hard to reject Paul’s meaning as husband/wife. If Paul was meaning generic men and women his argument really makes no sense. So i feel it best to go with husband/wife.
