It was a more congenial occupation for the vigilant head of the Church to watch over the extension of the faith than to promote the internal discipline of the fold of Christ by prosecutions for heresy. His gaze penetrated the mists of the far north, and we find Gregory forestalling (as indeed his great predecessor the first Gregory had done before him) the missionaries of our own day in the expedient of training young natives to preach the faith among their countrymen, over which there was much modern rejoicing when it was first adopted in recent days, as an entirely new and altogether wise thing. Gregory the Great had already practised it with his Anglo-Saxon boys: and Gregory VII. recommended it to Olaf, king of Norway, to whom he wrote that he would fain have sent a sufficient number of priests to his distant country: "But as this is very difficult because of the great distance and difference of language, we pray you, as we have also asked from the king of Denmark, to send to our apostolical court some young nobles of your country in order that being nourished with care in divine knowledge under the wings of St. Peter and St. Paul, they may carry back to you the counsels of the Apostolical See, arriving among you, not as men unknown, but as brothers--and preaching to you the duties of Christianity, not as strangers and ignorant, but as men whose language is yours, and who are yet trained and powerful in knowledge and morals." Thus, while the toils were gathering round his feet at home, and the most ancient centre of Christianity was ready to cast him out as a fugitive, the great Pope was extending the invisible links of Christian fealty to the ends of the earth.
