Last year (1925) the Olaus Petri Endowment greatly honoured the author by inviting him to deliver a few lectures on Origen at the University of Upsala. It was agreed that they should be published and we now offer them to the public exactly as they were delievered. There could be no question of expounding the entire thought of Origen in eight conferences. We have been compelled to pass over more than one important doctrine - for instance, his ideas on the Gnosis. Still less was it possible to set forth in these lectures the enormous mass of documents upon which our exposition of the theology of Origen is based.
