Pasagians were a religious sect appearing in Lombardy in the late 12th or early 13th century, and possibly appearing much earlier in the East. The name, if from the Italian passagieri meaning birds of passage, is either suggestive of an emigration from another place, or their iterant lifestyle. They observed the Law of Moses except in respect to sacrifices, and thus also were given the name Circumcisi, see Circumcision controversy in early Christianity. In their Christology they considered Christ the highest created being and a demiurge by whom all other creatures were brought into being. The Pasagians cited both the Old and New Testaments in support of their doctrine. Bonacursus is the chief authority of their history. As late as the eleventh century Cardinal Humbert of Mourmoutiers still referred to the Pasagians as a sect of Nazarenes, a Sabbath-keeping Christian body existing at that time (Strong’s Cyclopedia, New York, 1874, I, 660). Modern scholars believe it is the Pasagini who are referenced by Cardinal Humbert suggesting the Nazarene sect existed well into the eleventh century and beyond.(The Catholic writings of Bonacursus entitled "Against the Heretics"). It is believed that Gregorius of Bergamo, about 1250 CE, also wrote concerning the Nazarenes as the "Pasagini".
