Koskela on the importance of proclamation to apostolicity

"Only by proclaiming the gospel it has faithfully maintained can the church be truly apostolic."

Douglas M. Koskela, "'But who laid hands on him?'  Apostolicity and Methodist ecclesiology," Pro ecclesia 20, no. 1 (Winter 2011):  41 (28-42), italics mine.  This sentence stresses two of the "three primary ideas" the concept of apostolicity "has been employed to convey":  "continuity with the historical and visible church, the integrity of the church's life and witness, and the calling of the church to proclaim the gospel in word and deed" (29, italics original).
