Rebecca Larson, extreme Left, went to Waterloo Lutheran Seminary.
I entered the STM program at Yale Divinity in 1972. Stan Olson (ALC) entered the PhD program in New Testament studies. We were in two classes together. He taught at Luther Seminary and served as a parish pastor in New Ulm, of all places. He served as a bishop and then entered the ELCA hierarchy.
I recall a news report where he participated in or approved of Lutheran-Reformed Holy Communion. The ALC promoted joint communion with the Reformed while the LCA promoted joint worship with the Church of Rome. Merger allowed the ELCA to pursue unionism with anyone and everyone.
