Thank you for the welcome and especially for the prayers!Welcome! It's nice to have you here. It's also especially nice to hear from a pastor that understands these things (and is honest enough to admit it).
I will pray for you, your wife,.and the church you pastor. May the Lord Himself bless you all.
I've got a couple questions if you are willing. The first one is about patriarchy. I really consider polygamy to be an implication or extension of patriarchy, a sub-topic of patriarchy, with patriarchy being the more important principle. It sounds like you understand polygyny within the the larger Biblical framework of Covenant and male female relations. Am I correct in assuming that?
The second question pertains to you potentially taking a second wife. Do you consider polygyny to be acceptable for an elder/church pastor?
I understand polygyny to be lawful for men in general, but am not 100% certain about polygyny for church elders, based on the "husband of one wife" passages from 1st Timothy and Titus.
I think the main point is that the man is to be a faithful covenant keeping husband, and not a man who breaks faith with the wife of his youth.
I do wonder however if perhaps there might be another aspect. The elders lead the family of God, and perhaps wouldn't be able to do that and also have the time and ability to lead a large multi-wife, many child, patriarchal family of their own.
I do know several pastors that have large (6-7 child) monogamous families. Who knows but perhaps two wives with a similar number of children might potentially be easier? I can't really see a man with three wives and fifteen or more children leading well both his family and the church. I'm just wondering.
Also, I'm curious about your particular church background (Baptist, Assembly of God, Presbyterian/Reformed, Nazarene, Methodist, Charismatic, Lutheran, etc) if you were willing to share.
I totally understand if you prefer not to at this time. Discretion is important, especially in your situation.
Once again, welcome
As you noted, discretion is important. So forgive me for my unwillingness (at least right now) to give specifics.
Now, to your questions, first, I'm not entirely understanding the distinction which I think you're making between polygyny as extension of patriarchy and "polygyny within the larger Biblical framework of Covenant and male female relations." Would you mind unpacking that for me?
To the second, polygyny's neither commanded nor forbidden in the Scriptures in the sense that a man MUST have more than one wife or ONLY have one wife if he's to have a biblical marriage. That said, I do not think 1 Timothy 3's "μιᾶς γυναικὸς" for 'overseers' can be understood as forbidding clergy from polygyny unless we also change this same epistle's instructions for how widows are to be "covered" by their families or the congregation's elders (for whom the same μιᾶς γυναικὸς seems to grammatically-apply); now admittedly, this particular aspect I've only begun to think about over the last few weeks, so I could be completely wrong; Mr. Rambo, @FollowingHim , @frederick are probably better equipped to answer this point.
Nevertheless, even assuming that clergy also have this liberty, you bring up a point that I think is absolutely vital. As you rightly pointed out, "I can't really see a man with three wives and fifteen or more children leading well both his family and the church."
So while I think that patriarchy is non-negotiable, polygyny is optional (still assuming the above). Hence, to my mind, wisdom here is vital, and,for myself, to be honest, I'm really not sure if that would be a wise decision. So at this time, I'm content to simply let my request be made known to God as I continue to think thesw things through.
