The primarily sexual meaning of the word "sodomia" for Christians did not evolve before the 6th century AD. Roman Emperor Justinian I, in his novels no. 77 (dating 538) and no. 141 (dating 559) amended to his Corpus iuris civilis, and declared that Sodom's sin had been specifically same-sex activities and desire for them. He also linked "famines, earthquakes, and pestilences" upon cities as being due to "such crimes," during a time of recent earthquakes and other disasters (see Extreme weather events of 535–536). While adhering to the death penalty by beheading as punishment for homosexuality or adultery, Justinian's legal novels heralded a change in Roman legal paradigm, in that he introduced a concept of not only secular but also divine punishment for homosexual behavior.
