John,
One reality is that the church in the past and present is populated by males - and females - who do not know the LORD. Since this is the case they are living, acting like their father, the devil. Hence, you will find abuses in the 'church'.
I was surfing CNN a while ago and there was an article about a priest that abused young males and it went on to say how many priests - 6000 since the 1950s - have been accused of molesting children. We can say, well, that was the Catholic church, it does not happen in our church! Oh, really??!! I certainly hope you are right, but unfortunately, it is happening all over. Since this is the reality, how will a person confront a feminist, prove him/her wrong about their perverted view of Christianity?
It seems to be that to gloss over the abuses that occurred and are still happening would be dishonest. To admit, that yes, there have been wrongs done, but as a whole people are shocked when it does happen and therefore they react in horror when it becomes known. The fact that the perpetrators work to hide it is a testimony to the fact of them having a conscience against it or are aware of the anger their behaviors will incur. What if these things could happen and there would be no negative reactions to them?
I have learned that when I am confronted with inconsistencies among Christians, like my own church, that to be honest and admit there are problems, you do gain a hearing from your critics.
John, have you ever listened much to Ravi Zacharias sermons?
I suggest you go to www.rzim.org and find the archives of "Let My People Think" programs and listen. Ravi's ministry is to intellectuals and he may be able to give you some insight in how to deal with humanists although I am not aware he has any sermons dealing with the feminist issue, but the basic problems remain regardless of the particular issue.
John, you have a tough job - I certainly do not envy you, but do pray God will give you the grace to be honest and yet loving in your presentation. This will require a miracle since you are as a lamb among wolves. But God can and does give one grace to do His will. Methinks this will require for you a lot of prayer and listening to the voice of the Holy Spirit.
God bless..
