(Gr. tupos tes pisteos, “model of faith”). An edict issued by Emperor Constans II in 647 or 648 superseding Heraclius's Ecthesis. With a view to securing theological peace, it forbade anyone to assert either Monothelite* or Dyothelete* beliefs, and required that teaching should be limited to the definitions of the first five ecumenical councils. It was drawn up by Paul, the Monothelite patriarch of Constantinople. At the Lateran Council (649), Martin I condemned both the Ecthesis and the Typos, and was banished.
