Understanding, the prerequisite to obedience?

I was pleasantly surprised to hear that Wei En, Ngee Zheng's friend veiled at the Lord's Supper yesterday. I remember being so scared as I explained to her and elaine (another one of Ngee Zheng's friends) on the teaching of head-covering.

Its actually not easy for a guy to do so without having the fear that the sister who hears him won't feel 'offended' or 'oppressed'. I don't think the teaching is oppressive in itself, but today's cry of 'equal rights' has been extrapolated off the graph to the point where anyone who suggests a woman is not to do what a man should do, is labeled chauvinism.
I think that's quite sad. God is a God of 'equal rights', salvation is for 'the world'. He gives the sun and rain to both the righteous and the wicked. However, He has given different roles to both men and women, and it is good for us to humbly obey.

But i digress. I still wonder if Wei En veiled to conform to the meeting (where most, if not all, our women veil), or out of understanding and obedience to the Word of God. Nevertheless I'm thankful, because conforming or not, she has glorified God by suppressing the glory of man.
