The carafe and goblets are part of a Modern ecumenical line by Marshall Studios, a once-prominent pottery company that was based in Veedersburg, IN. I'd suggest looking in vintage stores or on eBay. Here's a scan of their catalog, where you can see the whole collection: http://marshallstudios.net/MS/ephemera_files/ms-cut-ecumenical.pdf

Thanks so much for the information and pictures!! I will look for the items on eBay. Thanks again!
