On June 8th I published a link for a view on a recent historical interpretation of Missouri Synod history.
A reader advised me that Paul Zimmerman had written on this subject but I have not read his take. Paul Zimmerman is an old friend of the Teigen family. He was at Bethany in the late 40s and early 50s and served most capably. He returned to his church home, the Lutheran Church-Missouri Synod, where he served as President of Concordia- Seward and Concordia- Ann Arbor.
Rev. Daniel Preus, Director of the Concordia Historical Institute, has also written on this subject. Follow the link http://www.confessionallutherans.org/papers/dantalk.htm
