IV. Ira Dei venit de coelo in filios diffidentiae. Zur Verbindung von Häresie und Sodomie aus kanonistischer Perspektive

Summary This paper questions the narrative widely used in historical research that from the time after the Fourth Lateran Council (1215), the canonical punishment of sodomy was tightened and sodomy was ultimately persecuted as heresy. Particular attention is paid to the ecclesiastical prosecution of heresy in the pontificate of Gregory IX in comparison to the treatment of the offence at the Lateran Councils of 1179 and 1215 as well as in the confession summa of Raymund of Peñafort. Due to the opposing presentations of the issue by Raymund and Gregory, this essay also contributes to the question of the relationship between the Pope and the compiler of the Liber Extra.
