‘The Word of the sermon is indeed a new Word and not a repetition of last Sunday’s sermon, but this does not mean that each sermon devaluates or extinguishes the previous sermons. If this were so, the New Testament could never speak about a “Church” and Paul could never refer to the message he had brought before … This is true because Jesus Christ’s presence among His people does not consist of appearances discontinuous in time, i.e., which occur’. – Dietrich Ritschl, A Theology of Proclamation (Richmond: John Knox Press, 1960), 72, 73.
