 Franciscans held that the vow of poverty requires renouncing ownership (dominium), but that using products owned by someone else (e.g., the Church) does not violate the vow. However, the question that divided them in the latter half of the thirteenth century was whether the vow requires that, even when merely using the goods of another, one adheres to strict standards of austerity, the so-called “poor use” (usus pauper). Olivi insisted on these strict standards but claimed that they are part of the vow only indeterminately. This means first that not every violation is a mortal sin, provided that one’s general tendency is to strive for spiritual humility by living poorly. It also means that what exactly counts as poor use depends on the circumstances and situation, since it is impossible to find a precise and fixed line between poor and lax use of commodities. In other words, Olivi admitted a certain latitude and flexibility in this notion (Burr 2001, pp. 51–53).
