Friedrich Lochner, discussing the chanting of the lessons in the divine service (Der Hauptgottesdienst, 1895) says:
The manner of liturgical recitation of the pericopes was followed throughout in Saxony, as also in Pomerania, the Mark, and part of Lower Saxony; in another part of Lower Saxony, and in Austria, it was left free whether the pericopes were to be spoken or sung, while in other areas, speaking was only permitted if the pastor did not have a sufficient gift for singing. And so it remained for some time. Thus Johann Schrader, in his Formular-Buch (1621) bears witness that it was still "in use in larger cities" and that in Magdeburg some years before, a book had been printed in folio "in which all the Epistles and Gospels were set to notation."
Thus Johannes Schrader is an interesting witness to the continuation of liturgical practice in the era of Lutheran Orthodoxy. With this in mind, I offer here a brief survey of his aforementioned Formular-Buch, using the 1670 edition (5th edition).
