They called themselves Jednota Bratrska--i.e., the Church of the Brethren. As this word "Jednota" means union, and is used in this sense in Bohemia at the present day, it is possible that the reader may think that instead of calling the Brethren a Church, we ought rather to call them the Union or Unity of the Brethren. If he does, however, he will be mistaken. We have no right to call the Brethren a mere Brotherhood or Unity. They regarded themselves as a true apostolic Church. They believed that their episcopal orders were valid. They called the Church of Rome a Jednota;[24] they called the Lutheran Church a Jednota;[25] they called themselves a Jednota; and, therefore, if the word Jednota means Church when applied to Lutherans and Roman Catholics, it must also mean Church when applied to the Bohemian Brethren. It is not correct to call them the Unitas Fratrum. The term is misleading. It suggests a Brotherhood rather than an organized Church. We have no right to call them a sect; the term is a needless insult to their memory.[26] As the Brethren settled in the Valley of Kunwald, the great object which they set before them was to recall to vigorous life the true Catholic Church of the Apostles; and as soon as they were challenged by their enemies to justify their existence, they replied in good set terms. "Above all things," declared the Brethren, at a Synod held in 1464, "we are one in this purpose. We hold fast the faith of the Lord Christ. We will abide in the righteousness and love of God. We will trust in the living God. We will do good works. We will serve each other in the spirit of love. We will lead a virtuous, humble, gentle, sober, patient and pure life; and thereby shall we know that we hold the faith in truth, and that a home is prepared for us in heaven. We will show obedience to one another, as the Holy Scriptures command. We will take from each other instruction, reproof and punishment, and thus shall we keep the covenant established by God through the Lord Christ."[27] To this purpose the Brethren held firm. In every detail of their lives--in business, in pleasure, in civil duties--they took the Sermon on the Mount as the lamp unto their feet. From the child to the old man, from the serf to the lord, from the acoluth to the bishop, the same strict law held good. What made the Brethren's Church shine so brightly in Bohemia before Luther's days was not their doctrine, but their lives; not their theory, but their practice; not their opinions, but their discipline. Without that discipline they would have been a shell without a kernel. It called forth the admiration of Calvin, and drove Luther to despair. It was, in truth, the jewel of the Church, her charm against foes within and without; and so great a part did it play in their lives that in later years they were known to some as "Brethren of the Law of Christ."
