At the end of his year of probation followed his solemn admission to the Order. Faithfully 'unto death' did Luther then promise to live according to the rules of the holy father Augustine, and to render obedience to Almighty God, to the Virgin Mary, and to the prior of the monastery. Before doing so, he put on anew the dress of his Order, which had been consecrated with holy water and incense. The prior received his vows and sprinkled holy water upon him as he prostrated himself upon the ground in the form of a cross. When the ceremony was over, his brethren congratulated him on being now like an innocent child fresh from the baptism. He was then given a cell of his own, with table, bedstead, and chair. It looked out upon the cloistered yard of the monastery. It was destroyed by a fire on March 7, 1872. [Illustration: Fig. 4.--LUTHER'S CELL AT ERFURT.] Luther now, by an inviolable promise, had bound himself to that vocation through which he aspired to gain heaven. The means whereby he hoped to realise his aspiration were abundantly provided for him in his new home. If he sought the favour of the Virgin and of other saints who should intercede for him before the judgment-seat of God and Christ, he found at once in his Order a fervent worship of the Virgin in particular, and all possible directions for her service. The doctrine of the Immaculate Conception, which Pius IX., in our own days, first ventured to raise into a dogma of the Church, was zealously defended by the Augustinians, and firmly maintained by Luther himself, even after the beginning of his war of Reformation. John Palz, one of his two theological teachers in the convent, wrote profusely in honour of this doctrine, and described all Christians as its spiritual children. Under its mantle, says Luther, he had to creep into the presence of Christ. From the multitude of other saints Luther selected a number as his constant helpers in need. We notice particularly that among these, in addition to St. Anne and St. George, was the Apostle Thomas; from him who himself had once betrayed such cowardice and want of faith he might well hope for peculiar sympathy. We have already mentioned the set prayers which filled up a great portion of the day. He was required above all things to learn and repeat them accurately, word by word. Afterwards, as he tells us, the _Horae_ were read aloud after the manner of magpies, jackdaws, or parrots.
