Here's how it shakes out (for those, formerly from Twin Falls, who might care):
Twin Falls Stake
11th (formerly in the Kimberly stake)
15th (also from Kimberly stake)
Blue Lake Branch
Twin Falls South Stake (the new one)
17th (all formerly in the Twin Falls Stake)
other wards from TF West stake (don't remember exactly which ones)
same old wards, minus the ones moving to the South Stake
same wards, minus 11th and 15th (but keeping the 19th ward, which is actually in Twin Falls)
Besides redrawing boundary lines to accommodate these changes, it also means releasing quite a few folks from stake callings. Fully half of the Twin Falls stake high council will be in the new stake, and one member of the stake presidency. Every auxiliary leader except YM (i.e. YW, Primary, RS) will be released to go to the new stake. No ward boundaries are changing, so no changes in bishoprics, etc., but lots of folks getting moved around and adjusting to new things.
Here's something that may be a bit hard for some folks to swallow. We haven't even dedicated the new stake center adjacent to the temple and folks who thought it would be "their" stake center have to (get to) go back to the Maurice St. building. That old building still has plenty of life left in it, but it is awkward and a bit of a pain sometimes. I think its accurate to say that people have a love/hate relationship with that building.
The various sessions of stake conference to work out the details of the change will be held in the new building and then folks in the South stake are moving back to Maurice St. They'll get a new building eventually, but not in the next several years, I'd bet. They don't have land in that part of the valley yet, as far as I know (which ain't much, really).
Anyway, what does it matter? Beyond who we get to see at stake conference or whatever, it means that opportunities for growth and service in the Magic Valley expand. Each of the stakes has 8-9 units in it, but the potential for growth still exists-- particularly in the South and West stakes and the Kimberly stake (the Twin Falls stake is kind of land-locked).
The change also means a new stake president, which means a general officer from the church will preside at the stake conference and select that president. Because most church administration at the local level comes from stake presidents, members of the church view them in fairly high regard. Speaking rather personally, stake presidents set the tone for church service and administration, and give direction to what many lay members do from day to day and week to week. Without endowing them with too much supernatural power, I don't think it is too much of a stretch to say that they speak for God in this part of the vineyard. That's pretty cool and pretty important.
The dedication of the temple was just one of many moving experiences of the summer. I anticipate that the creation of a new stake will be another-- particularly if we go in to it looking for the hand of God in what is done.
On a related note-- related to spirituality, anyway-- I've been rereading Marilynne Robinson's Gilead so I can read the companion novel that was just released, Home. The first takes the form of letters from an aged father to his very young son and takes place in Gilead, Iowa (a fictional place). It touches, in part, on the father's relationship with a dear friend and that friend's wayward son. The second takes up the same time period, but from the POV of the dear friend. I read the first 3-4 chapters of Home before realizing that I didn't remember enough of Gilead to recognize their points of intersection (and finding such textual common ground is one of my favorite parts of reading), so I'm back to Gilead today. I hope to finish it in the next day or so, so I can read Home and then be worth something to my classes again. In the meantime, I'm WAY distracted by having something delicious to read.
The protagonists of Gilead and Home are both preachers and I have enjoyed their examinations of spiritual matters. Perhaps I'll post about some of them soon.
*"stake" is roughly equivalent to diocesis, whereas "ward" is roughly equivalent to parrish.
