Another option to consider is a 24-70mm f/2.8 lens from a third-party such as Tamron or Sigma. Those are not quite as expensive, but they often don’t hold their value quite so well either.
Definitely check out used sources such as Robert’s Camera and KEH as well as Adorama and B&H Photo. Many of those retailers also sell on eBay: e.g. here’s one from Robert’s Camera on eBay: https://www.ebay.com/itm/Nikon-Nikkor-AF-S-24-70mm-f2-8-G-ED-IF-ASPH-Lens-AFS-860/203006694554
Keep in mind that 24mm x 1.5 crop factor (for a DX camera) equals 36mm. You’ll probably want something wider for indoor shots if you want to get the whole congregation in one shot! Ken Rockwell recommends that if you have a DX camera you get the Nikon 17-55mm f/2.8 instead.
