Women and a Synagogue Prayer

I came across an interesting quote about women in the church on the NT Wright page from a paper entitled, "Women’s Service in the Church: The Biblical Basis"

Remember the synagogue prayer in which the man who prays thanks God that he has not made him a Gentile, a slave or a woman – at which point the women in the congregation would [thank] God ‘that you have made me according to your will’. I think Paul is deliberately marking out the family of Abraham reformed in the Messiah as a people who cannot pray that prayer, since within this family these distinctions are now irrelevant.
