Agricola was born at Eisleben, whence he is sometimes called Magister Islebius. He studied at Wittenberg, where he soon gained the friendship of Martin Luther. In 1519 he accompanied Luther to the great assembly of German divines at Leipzig, and acted as recording secretary. After teaching for some time in Wittenberg, he went to Frankfurt in 1525 to establish the Protestant mode of worship. He had resided there only a month when he was called to Eisleben, where he remained till 1526 as teacher in the school of St Andrew, and preacher in the Nicolai church.
Controversy
In 1536 he was recalled to teach in Wittenberg, and was welcomed by Luther. Almost immediately, however, a controversy, which had been begun ten years before and been temporarily silenced, broke out more violently than ever. Agricola was the first to teach the views which Luther was the first to stigmatize by the name Antinomian, maintaining that while non-Christians were still held to the Mosaic law, Christians were entirely free from it, being under the gospel alone. . After he wrote an attack on Luther shortly after Luther had given him shelter when he was fleeing persecution, Luther had nothing further to do with him.
Restoration and later life
As a consequence of the bitter controversy with Luther, in 1540 Agricola left Wittenberg secretly for Berlin, where he published a letter addressed to Frederick III, Elector of Saxony, which was generally interpreted as a recantation of his prior views. Luther, however, seems not to have so accepted it, and Agricola remained at Berlin. Joachim II Hector, Elector of Brandenburg, having taken Agricola into his favour, appointed him court preacher and general superintendent. He held both offices until his death in 1566, and his career in Brandenburg was one of great activity and influence. Along with Julius von Pflug, bishop of Naumburg-Zeitz, and Michael Helding, titular bishop of Sidon, he prepared the Augsburg Interim of 1548, a proposed settlement under which Protestants would accept all Catholic authority, being permitted to retain the Protestant teaching on justification but otherwise compelled to accept Catholic doctrine and practice. From that time, he was an outcast among Protestant theologians. It was an irony that one of the most radical Reformers ended his life viewed as having capitulated to Catholics. He endeavored in vain to appease the Adiaphoristic controversy. He died during an epidemic of plague on September 22, 1566 in Berlin.
Writings
Agricola wrote a number of theological works. He was among the first to make a commentated collection of German proverbs. The first volume contains 300 proverbs and was published in 1529 ; the second volume contains 450 proverbs and was published in 1530. A revised edition containing the seven hundred and fifty proverbs of the previous two volumes was published in 1534 and later republished with updated orthography, for example, in Wittenberg in 1592.
In literature
In 1836, Robert Browning used him as the subject of an early poetic soliloquy, "Johannes Agricola in Meditation".
