  The Franciscans maintained that they lived the most perfect life that was humanly possible, following the model of Christ and the apostles who, they claimed, possessed nothing either as individuals or in common. John XXII not only denied that Christ and the apostles had no possessions, but he also declared the Franciscan position to be heretical. The resulting quarrel came to touch on such issues as usury, ownership of property, disposal of property, natural and divine law and rights, papal infallibility, and ultimately the basis of sovereignty.
