The statement is a little bit troubling in one respect, and absolutely correct in another. I think it absolutely true that there is absolutely NO difference between male and female at the cross. Where experiencing the full power of God's resurrection is concerned there is no difference.
Gal 3:27-28
(27) For as many of you as have been baptized into Christ have put on Christ.
(28) There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
The quote does hint at the idea that Christ freed women from the curse of being in subjection to their husbands. This would not be a Biblical idea at all. There is still a Godly and proper order to the husband/wife relationship that has not changed.
Eph 5:20-28
(20) Giving thanks always for all things unto God and the Father in the name of our Lord Jesus Christ;
(21) Submitting yourselves one to another in the fear of God.
(22) Wives, submit yourselves unto your own husbands, as unto the Lord.
(23) For the husband is the head of the wife, even as Christ is the head of the church: and he is the saviour of the body.
(24) Therefore as the church is subject unto Christ, so let the wives be to their own husbands in every thing.
(25) Husbands, love your wives, even as Christ also loved the church, and gave himself for it;
(26) That he might sanctify and cleanse it with the washing of water by the word,
(27) That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish.
(28) So ought men to love their wives as their own bodies. He that loveth his wife loveth himself.
However this scripture must be taken in all of its statement and context. Although my wife subjects herself to me just as I subject myself to Christ there is also a reality of my own submission to her according to verse 21. There is a mutual submission to one another in Christ and in another sense a submission of wife to husband in the Biblical order of things.
