R.C Sproul: Headcovering

The issue is this: If you feel the Holy Spirit convicts you to wear one, wear one. If you don't feel the Holy Spirit convicting you to wear one, then you don't need to wear one. Reading on of R. C. Sproul books on the topic:

For example, when Jesus sent out the seventy disciples on a mission of evangelism, he told them to take no shoes with them. That does not mean that all preaching and all evangelism for all times and all places has to be done in bare feet. Billy Graham is not sinning by wearing shoes when he preaches the gospel. Bu there are many questions like that that are not so obvious. In that whole context of the eleventh chapter of 1 Corinthians, women are called to cover their heads with a veil as a sign of their willingness to submit to the leadership or headshiop of their husbands. There are three elements here: 1. The submission of the wife to the husband as the head of the home 2. The covering of the head 3. The covering of the head by a veil How much is principle and how much is custom? Many Christians believe that we should no longer tell women to submit to the headship of their husbands. Therefore, women don't have to cover their heads. Others say that the headship principle still stands in the home, but the covering of the head was cultural custom that does not carry over into our day, and therefore the veil would be insignificant as well. The third view of this passage is that it is describing a principle, and that women must cover their heads and use veils to do so. I am convinced that when Paul says the women are to cover their heads, he is basing that action on how God created male and female. It would seem to me, using a principle of interpretation of what we call hermeneutics, that if there ever an indication of a perpetual ordinance in the church, it is that which is based on an appeal to Creation. I'm persuaded that the principle of covering the head is still in effect because it was built into creation. And even though it's not culturally accepted anymore in our society, I still believe it's priniciple. I don't think it matters one bit whether it's a babushka, a veil, or a hat, but I think that the symbol should remain intact as a sign of our obedience to God.
