Bishop, you said a mouthful ... I don't think it is necessarily a biblical doctrinal issue.. but then again.. you must submit to the ORDER and model of ministry that GOD has set you under... that IS biblical. First the natural then the spiritual.. when we sat under order of our parents we didn't agree with everything but we submitted to the ORDER else we suffered.. how will we not do the same in the house of our spiritual parents.
Truthfully it has never been about the clothes - pants or otherwise - but about the set ORDER of that HOUSE. Submit to the order. If wearing pants means that much to you then you have a decision to make. But be careful in doing so.
