the old doctrine of justification by works was modified; and thus the Brethren's Church became the first organized Evangelical Church in Europe.[19] And Luke designed to make her the strongest, too. His energy never seemed to flag. As he wished to establish the ministry more firmly, he had the number of Bishops enlarged, and became a Bishop himself. He enlarged the governing Council, with his friend Procop of Neuhaus as Ecclesiastical Judge. He beautified the Church Services, and made the ritual more ornate. He introduced golden communion cups and delicately embroidered corporals, and some of the Brethren actually thought that he was leading them back to Rome. He gave an impulse to Church music, encouraged reading both in Priests and in people, and made a use of the printing press which in those days was astounding. Of the five printing presses in all Bohemia, three belonged to the Brethren; of sixty printed works that appeared between 1500 and 1510, no fewer than fifty were published by the Brethren; and of all the scribes of the sixteenth century, Luke was the most prolific. He wrote a "Catechism for Children." He edited the first Brethren's hymn book (1501), the first Church hymnal in history. He published a commentary on the Psalms, another on the Gospel of St. John, and another on the eleventh chapter of 1 Corinthians; he drew up "Confessions of Faith," and sent them to the King; and thus, for the first time in the history of Bohemia, he made the newly invented press a mighty power in the land. And even with this the good Bishop was not content {1491.}. If the Brethren, thought he, were true to their name, they must surely long for fellowship with others of like mind with themselves. For this purpose Luke and his friends set off to search for Brethren in other lands. Away went one to find the pure Nestorian Church that was said to exist in India, got as far as Antioch, Jerusalem and Egypt, and, being misled somehow by a Jew, returned home with the wonderful notion that the River Nile flowed from the Garden of Eden, but with no more knowledge of the Church in India than when he first set out. Another explored the South of Russia, and the third sought Christians in Turkey. And Luke himself had little more success. He explored a number of Monasteries in Greece, came on to Rome {1498.}, saw the streets of the city littered with corpses of men murdered by Cæsar Borgia, picked up some useful information about the private character of the Pope, saw Savonarola put to death in Florence, fell in with a few Waldenses in the Savoy, and then, having sought for pearls in vain, returned home in a state of disgust, and convinced that, besides the Brethren, there was not to be found a true Christian Church on the face of God's fair earth. He even found fault with the Waldenses.
