“The classical text of the threefold good, or threefold advantage (tripla commoda), is found where Bruno gives an account of Otto III’s project of choosing some of the more fervent disciples of Romuald as missionaries to Poland. There they were to build a monasterium in Christian territory near an area where pagans dwelt, secluded and surrounded by woods: ‘This would offer a threefold advantage: the cœnobium, which is what novices want; golden solitude, for those who are mature and who thirst for the living God; and the preaching of the gospel to the pagans, for those who long to be freed from this life in order to be with Christ’.”
