You will never find Hermann Sasse teaching like Walther, Pieper, the Synodical Conference... or like Luther on the true Doctrine of Justification. Oh, he may speak the words "justification by faith alone" which are very Lutheran sounding words, but what he means is a "faith" that in the final analysis is like the teaching of the opponents of the old (German) Missouri Synod... a "faith" that is actually meritorious for salvation... synergism. That is why Sasse opposed Pieper's Brief Statement of 1932 ... and it shows why Pieper so forcefully teaches the correct doctrine of Conversion - see paragraphs 10-16. Now which is the truly confessional Lutheran: Hermann Sasse or Franz Pieper? (Better study carefully the Lutheran Book of Concord).
In this portion is the greatest teaching of John 3:16 since the days of Martin Luther and the Reformation. It is precisely the meaning of John 3:16 that is "The Lutheran Difference".
