On the evening of June 13, on Tuesday after Trinity Sunday, Luther invited Bugenhagen, Jonas, Lucas Cranach and wife, and a professor of jurisprudence, Apel (an ex-Dean of the Cathedral of Bamberg, who had himself married a nun), to his house, and in their presence was joined in matrimony to Catharina von Bora in the name of the Holy Trinity. Bugenhagen performed the ceremony in the customary manner. On the following morning he entertained his friends at breakfast. Justus Jonas reported the marriage to Spalatin through a special messenger. He was affected by it to tears, and saw in it the wonderful hand of God. On June 27 Luther celebrated his wedding in a more public, yet modest style, by a nuptial feast, and invited his father and mother and his distant friends to “seal and ratify” the union, and to “pronounce the benediction.” He mentioned with special satisfaction that he had now fulfilled an old duty to his father, who wished him to marry.*
