is a kind of Prophet; in him too there is required to be a light of inspiration, as we must name it. He presides over the worship of the people; is the Uniter of them with the Unseen Holy. He is the spiritual Captain of the people; as the Prophet is their spiritual King with many captains: he guides them heavenward, by wise guidance through this Earth and its work. The ideal of him is, that he too be what we can call a voice from the unseen Heaven; interpreting, even as the Prophet did, and in a more familiar manner unfolding the same to men.
Yet it will suit us better here to consider them chiefly in their historical character, rather as Reformers than Priests. There have been other Priests perhaps equally notable, in calmer times, for doing faithfully the office of a Leader of Worship; bringing down, by faithful heroism in that kind, a light from Heaven into the daily life of their people; leading them forward, as under God's guidance, in the way wherein they were to go. But when this same way was a rough one, of battle, confusion and danger, the spiritual Captain, who led through that, becomes, especially to us who live under the fruit of his leading, more notable than any other. He is the warfaring and battling Priest; who led his people, not to quiet faithful labor as in smooth times, but to faithful valorous conflict, in times all violent, dismembered: a more perilous service, and a more memorable one, be it higher or not. These two men we will account our best Priests, inasmuch as they were our best Reformers.
So, the priest who serves in quiet times, who does nothing more than raise his congregation to new spiritual heights, who helps them to do good and avoid evil, is no hero to Carlyle. To be a hero you have to have served in tumultuous times and been the equivalent of a warrior priest. Luther certainly fits the bill. As the one who finally found a way to break the grip on the people of a corrupt Roman Catholic Church, he is generally considered the founder of the Reformation. Others had come before him: Wycliffe, Hus, even perhaps the Waldensians, are part of the Reformation equation.
