Readings in Social Ethics: Bonaventure, A Defence of the Mendicants (selections), in From Irenaeus to Grotius: A Sourcebook in Christian Political Thought 100-1625, ed. Oliver O’Donovan and Joan Lockwood O’Donovan, pp. 312-19. The references below are to section number.
- Bonaventure cites a number of authorities in his exposition, including Augustine, Jerome, Bede, Rabanus Maurus, Gregory the Great, and Bernard of Clairvaux.
- The apostolic way of life is described as consisting in “models of perfection,” and therefore imposing “no obligation on those who have not freely professed this pattern of life and taken vows.” 
- There are four kinds of “community of goods,” corresponding to four different sources of right .
- The right of natural necessity: “anything capable of sustaining natural existence, though it be somebody’s private property, may belong to someone who is in the most urgent need of it. This kind of community of goods cannot be renounced. It derives from the right that naturally belongs to man as God’s image and noblest creature, on whose behalf all other things on earth were made.” This right functions at the personal level, and is the basis for the moral judgment that in certain extreme circumstances, what would otherwise be theft of necessary life-sustaining goods may be morally justified.
- The right of brotherly love: “everything belongs to the righteous, and the private property of individuals is common to all by virtue of sharing which is natural to love…. This kind of community of goods absolutely may not be renounced. It derives from a right poured into us by God, the right by which ‘the dove’ (i.e., the universal church) is assured its unity, a unity of sharing, from which no one can depart without defiance of the law of God which enfolds all things in love.” This right functions at the level of social responsibility to care for those who belong to the universal church. See Paul’s command to do good to everyone, “especially to those who are of the household of faith.”
- The right of worldly civil society: “there is a common political identity within a single empire, kingdom, or city-state; there is a common profit and loss within a single association, e.g., of merchants or wrestlers; there is a common inheritance within a single family that has not split up. This kind of community of goods must be renounced to attain evangelical perfection, because this kind of community implies individual property. It is derived from a humanly instituted right which contains provisions that may incidentally prove an obstacle to good or an encouragement to evil, and is therefore incompatible with evangelical perfection.” This right functions on the level of political society. The right to private property may be given up voluntarily in pursuit of the model of apostolic perfection. The emphasis here is on the temptation to covetousness that private property occasions.
- The right of ecclesiastical endowment: “All goods bestowed upon the churches are dedicated to the Lord to provide for the ministry and for the poor. This kind of community of goods, which is found in all collegial churches with possessions, need not be renounced to attain perfection since it can be maintained without prejudice to perfection, as is clear in the case of bishops and religious who are holy and perfect…. Yet this kind of community may be renounced without prejudice to perfection – in pursuit of it, rather – since it springs not only from divine right but human, it is not only spiritual but temporal, too; and since, though it excludes individual property, collegial property is allowed, and the share of every member of the college must be understood not merely as use but as ownership.” This right functions at the bridge between the second and third types of right. The administration and use of goods falls to those who are in places of responsibility in the church. Insofar as these goods are defined as “ecclesiastical” and not of more common worldly ownership, there is a distinction at the level of “worldly civil society.” The individual Christian may pursue the model of apostolic perfection in renouncing this sort of collegial ownership, but since the apostles themselves administered the property of the church, this responsibility need not be renounced to be perfect.
- “There are four possible relations to temporal goods: property, possession, usufruct, and simple use. The life of mortals may be sustained without the first three, but the last is a necessity. There can, then, be no profession of renunciation of temporal things which extends to their use.”
