Danny,

My firsthand observations show that there is a wide variety of outcomes. Churches that are focused on "liberal" issues such as social justice are more likely to install a female as pastor and likely to struggle to grow or retain members because they are not focused on seeking and following the Holy Spirit. In contrast, I have seen several others where their focus is on following the Holy Spirit have done well and one of them was established by a woman. 

I remind readers here that the largest and perhaps the fastest-growing SDA church in the world was established by a woman who still is head pastor. That church is in the northern part of Vietnam near the border with China. We should not be discounting in any way the potential for any person to minister in any role if they are called to it by the Holy Spirit, so their calling should be the question, not their gender.
