I've never been to a church who enforced women to cover their heads.

It's all in how your interpret God's Word I suppose. I personally believe that there was instruction in the New Testament that was for the believers during that time and that it wasn't meant for the church during every age.

I believe that enforcing a rule for women to cover their heads is pretty legalistic and strays from the true gospel.

But I'm fallible and now I only see in part. So I could very well be wrong.

Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified. - Galatians 2:16
