The Innovation of Christ with Regard to the Dignity & Equality of Women

Some of my favorite passages of summary from Pope John Paul II's Papal Encyclical "On the Dignity and Vocation of Women":

Christ's attitude to women confirms and clarifies, in the Holy Spirit, the truth about the equality of man and woman. One must speak of an essential "equality", since both of them - the woman as much as the man - are created in the image and likeness of God. Both of them are equally capable of receiving the outpouring of divine truth and love in the Holy Spirit. Both receive his salvific and sanctifying "visits".
 
The fact of being a man or a woman involves no limitation here, just as the salvific and sanctifying action of the Spirit in man is in no way limited by the fact that one is a Jew or a Greek, slave or free, according to the well-known words of Saint Paul: "For you are all one in Christ Jesus" (Gal 3:28).

The "innovation" of Christ is a fact: it constitutes the unambiguous content of the evangelical message and is the result of the Redemption. However, the awareness that in marriage there is mutual "subjection of the spouses out of reverence for Christ", and not just that of the wife to the husband, must gradually establish itself in hearts, consciences, behaviour and customs. This is a call which from that time onwards, does not cease to challenge succeeding generations; it is a call which people have to accept ever anew. Saint Paul not only wrote: "In Christ Jesus... there is no more man or woman", but also wrote: "There is no more slave or freeman". Yet how many generations were needed for such a principle to be realized in the history of humanity through the abolition of slavery! And what is one to say of the many forms of slavery to which individuals and peoples are subjected, which have not yet disappeared from history?

But the challenge presented by the "ethos" of the Redemption is clear and definitive. All the reasons in favour of the "subjection" of woman to man in marriage must be understood in the sense of a "mutual subjection" of both "out of reverence for Christ".
