The Swedish High Church movement has, ever since its breakthrough in the 1930s, in one way or another struggled to accentuate the sacrificial motif in the celebration of the Mass. This is something that especially can be noted in the missals that have been produced within the movement, and by persons connected to it. The doctrine of the Sacrifice of the Mass, as this theory is known traditionally, has been and still is frequently discussed within the High Church movement itself and also outside its context, which means that the subject still is of interest. This fact raises questions such as: what sacrificial motifs can be found in the High Church missals? Can one distinguish a joint “High Church understanding” of the Sacrifice of the Mass in these missals? Has this understanding changed through the years, if so: how? By analysing missals from 1930 until 2008 – through a careful survey of relevant liturgical sections, taking church history into consideration and according to a narrowed definition – this essay presents a wide range of theological and sacrificial motifs. With this in mind a very variable or “billowing” development of the understanding of the Sacrifice of the Mass is observed in the missals, rather than a chronological and straight line of development: an understanding sometimes characterized by theological caution and alternately by theological clarity and radicalism.
