My denomination doesn't have women as Senior Pastors. I personally see some merit, particularly in this day and age where Pastors are also counsellors, for having women on pastoral staff.
I also see very little difference between prophesying and preaching.
And yes, Phoebe was a deacon.
I take that back. There probably are some, but the "official position" is that there shouldnt' be.
Does your church structure have deacons?
A deacon in the church is the first rank of the ordained ministry, but is not a priest. Women deaocns in the early Church had no functions comparable to male deacons who serve with priests the Divine Liturgy. The Scripture is clear that women should not speak in the church.
