re #42: I did some research because I was curious, and in case anyone cares, “things have changed” is correct, and “mistaken” may well also be correct.
Western Theological Seminary was invited to relocate from Chicago to Evanston in 1929 by Northwestern, and stayed there as Seabury-Western Theological Seminary until about 2013. That was the “other” seminary.
“things have changed”= They sold their land to Northwestern and then moved back to Chicago in about 2013 as Bexley Seabury Seminary.
“mistaken may also be correct” because there’s nothing I can find suggesting that the seminaries were actually affilates of Northwestern.
The Northwestern alum who asserted it may have made the assumption due to subsequent attendance at Columbia, whose nearby seminaries (Union and JTS) are indeed affiliates of the university.
