Christian seems to think that the main idea is that in this sacrament one _does_ something—makes a profession of Christianity. The old view went a long way towards keeping people right in spite of errors, while the modern view does a great deal towards leading them wrong in spite of truth. All these things combine to show us how there was a simple evangelical faith among pious mediæval Christians, and that their lives were fed upon the same divine truths which lie at the basis of Reformation theology. The truths were all there, as poetic thoughts, as earnest supplication and confession, in fervent preaching or in fireside teaching. When mediæval Christians knelt in prayer, stood to sing their Redeemer’s praises, spoke as a dying man to dying men, or as a mother to the children about her knees, the words and thoughts that came were what Luther and Zwingli and Calvin wove into Reformation creeds, and expanded into that experimental theology which was characteristic of the Reformation. When the printing-press began in the last decades of the fifteenth century to provide little books to aid private and family devotion, it is not surprising, after what has been said, to find how full many of them were of simple evangelical piety. Some contained the Lord’s Prayer, the Ten Commandments, the Apostles’ Creed, and occasionally a translation or paraphrase of some of the Psalms, notably the 51st Psalm. Popular religious instructions and catechisms for family use were printed. The Catechism of Dietrich Koelde (written in 1470) says: “Man must place his faith and hope and love on God alone, and not in any creature; he must trust in nothing but in the work of Jesus Christ.” The _Seelenwurzgartlein_, a widely used book of devotion, instructs the penitent: “Thou must place all thy hope and trust on nothing else than on the work and death of Jesus Christ.” The _Geistliche Streit_ of Ulrich Krafft (1503) teaches the dying man to place all his trust on the “mercy and goodness of God, and not on his own good works.” Quotations might be multiplied, all proving the existence of a simple evangelical piety, and showing that the home experience of Friedrich Mecum (Myconius) was shared in by thousands, and that there was a simple evangelical family religion in numberless German homes in the end of the fifteenth century. § 5.
