On 9 October, 1523, Huldrych Zwingli published his briefest explanation of the meaning of the Lord’s Supper- De canone missae libelli apologia. In its first printing it ran 2 folio pages and in its ‘official’ critical edition it’s just a little over 5 pages. These little writings were called Flugschriften, because they literally ‘flew’ off the press.
What Zwingli abandons for the sake of space he compensates for in specificity. This is the clearest exposition of the Lord’s Supper in any of Zwingli’s publications. It has never been translated into English and isn’t available in any edition of Zwingli’s works but the Critical edition in the Corpus Reformatorum series.
