Julianna, I must be honest in saying that I am already nervous of a woman's only ministry that is not run in conjunction with a husband or the oversight of a spiritual father.

Apostle Paul was even tough on this one and as an apostolic father did not allow a woman to stand up on her own to preach. However he certainly did condone Priscilla and Aquila to minister (even though it was clear that she took the primary role in that couple)

While I do believe that modesty is certainly important in ministry, I do not believe that we should compromise who we are either! It is clear that this woman has received some doctrine or teaching that you will find goes beyond just "what you wear." If anything, this is where you need to point your concern.

What might just be starting off as a few guidelines for dress might have their root in a doctrinal belief that she has that spreads into other areas as well. In the end, you might find yourself battling some strange doctrinal issues in the foundation of this ministry. If you feel that this opportunity is from the Lord, then you need to ask this woman, what she bases her beliefs on.

Try to see if this belief system goes beyond just what you wear and into other areas of how the ministry is run. It might end up pointing to a very feminist outlook in the way the ministry is run, which if that is the case, she is asking to fall into deception.

At the end of the day, you must also listen to your spirit! Do not be afraid to be different or to rock the boat. It's clear to me that the Lord is already putting some warning bells inside of you, so to ignore these would not be a good idea. You already sense that something is wrong, even though you cannot put your finger on it. Heed these warnings and just keep your eyes and ears open. If this sense of caution continues I think it would be good if you decline the offer.

It might even be that the Lord has something entirely different for you and the enemy is trying to side track you. I wish you blessing on this journey! I know how it can be filled with rocks and stumbling stones sometimes, but I also
know that the Holy Spirit will not let go of your hand! Press on forward and I know the way will become more clear.
