The most important figure in early Icelandic Lutheranism was, however, Gissur Einarsson, who during a period of study in Germany learned about the Reformation. In 1536, he became assistant at the Skálholt bishopric, though he still did not formally embrace Lutheranism. When Lutheranism became the state religion of Denmark and Norway under king Christian III, the king tried to convert Iceland too. In 1538, the "Church Ordinance" (the royal invitation to convert) was put before the two bishops Øgmundur and Jón at the Althing, but it was rejected. Then Christian III ordered the dissolution of the monasteries. Bishop Øgmundur, now old and almost blind, chose Gissur Einarsson as his successor. He was examined by theologians in Copenhagen and in 1540 the king appointed him as the superintendent of Skálholt. Gissur was only 25 years old and it was difficult for him to maintain power, especially as he was opposed by the clergy and even by the old bishop. A royal emissary was sent to uphold the ordinance, and Øgmundur was arrested and died on the way to Denmark. The ordinance was accepted in Skálholt, but rejected by Jón Arason in Hólar. Bishop Gissur, who was ordained by the Danish bishop Peder Palladius, reorganised the church in his diocese according to Lutheran principles, including the suppression of Catholic ceremonies and the exhortation of clergy marriage. He entrusted Oddur Gottskálksson with the translation of German sermons, and he himself translated parts of the Old Testament and the Church Ordinance.
