OF the writings of John Huss of Bohemia, the Treatise on the Church is the most important.1 From its pages the charges were drawn upon which the author was pronounced a heretic by the council of Constance and the same day, 'July 6, 1415, burned at the stake. It was written in Latin and the translation, here offered, is the first that has appeared in English and seems to be the first to be issued in any language. It is offered as a help in the appreciation of a memorable man who deserves well of Western Christendom and as a contribution to the study of ecclesiology.(...)"
Jan Hus c. 1369 – 6 July 1415), often referred to in English as John Hus or John Huss, was a Czech priest, philosopher, reformer, and master at Charles University in Prague. After John Wycliffe, the theorist of ecclesiastical Reformation, he was, before Luther, Calvin and Zwingli, the first actual Church reformer.
He is famed for having been burned at the stake for heresy against the doctrines of the Catholic Church, including those on ecclesiology (the branch of theology concerned with the nature, constitution and functions of the Church), the Eucharist (the most important Christian sacrament), and other theological topics. Hus was a key predecessor to the Protestant movement of the sixteenth century, and his teachings had a strong influence on the states of Europe, most immediately in the approval for the existence of a reformist Bohemian religious denomination, and, more than a century later, on Martin Luther himself.
Between 1420 and 1431, the Hussite forces defeated five consecutive papal crusades against followers of Hus. Their defense and rebellion against Roman Catholics became known as the Hussite Wars. A century later, as many as 90% of inhabitants of the Czech lands were non-Catholic and followed the teachings of Hus and his successors.
I won't offer a theological commentary, but I will say that Hus's writings are great for their theological clarity. I actually understand his views pretty well when I'm reading.
Also, this is a very significant historical resource in the study of the rise of Protestant ideology in the centuries before Luther.
