"There is my mass." Then raising his eyes to heaven, he solemnly said, "O Lord, if in the day of judgment thou chargest me with not having been at mass, I will say to thee with truth, 'Lord, thou hast not commanded it. Behold thy law. In it I have not found any other sacrifice than that which was immolated on the altar of the cross.'" In 1535 Calvin's celebrated "Institutes of the Christian Religion" were published, the great reformer then residing in the city of Basle. This great work became the banner of the Protestants of France. It was read with avidity in the cottage of the peasant, in the work-shop of the artisan, and in the chateau of the noble. In reference to this extraordinary man, of whom it has been said, "On Calvin some think Heaven's own mantle fell, While others deem him instrument of hell," Theodore Beza writes, "I do not believe that his equal can be found. Besides preaching every day from week to week, very often, and as much as he was able, he preached twice every Sunday. He lectured on theology three times a week. He delivered addresses to the Consistory, and also instructed at length every Friday before the Bible Conference, which we call the congregation. He continued this course so constantly that he never failed a single time except in extreme illness. Moreover, who could recount his other common or extraordinary labors? I know of no man of our age who has had more to hear, to answer, to write, nor things of greater importance. The number and quality of his writings alone is enough to astonish any man who sees them, and still more those who read them. And what renders his labors still more astonishing is, that he had a body so feeble by nature, so debilitated by night labors and too great abstemiousness, and, what is more, subject to so many maladies, that no man who saw him could understand how he had lived so long. And yet, for all that, he never ceased to labor night and day in the work of the Lord. We entreated him to have more regard for himself; but his ordinary reply was that he was doing nothing, and that we should allow God to find him always watching, and working as he could to his latest breath." Calvin died in 1564, eleven years after the birth of Henry of Navarre, at the age of fifty-five. For several years he was so abstemious that he had eaten but one meal a day.[A] [Footnote A: In reference to the execution of Servetus for heresy, an event which, in the estimation of many, has seriously tarnished the reputation of Calvin, the celebrated French historian M. Mignet, in a very able dissertation, establishes the following points:
