Everyone agrees we have duties of charity, however restrictive a view they take of our duties of justice. This article argues that duties of charity, properly understood, require institutions akin to those that advocates of robust duties of justice recommend. Notice that duties of charity can sometimes be stronger than duties of justice; and those owed duties of justice cannot complain in which cases when the former are discharged rather than the latter when both cannot be. But duties of charity, being imperfect, benefit from institutional specification making it clear who owes what to whom. Institutions do that by 'consolidating' imperfect duties of charity. Such institutions would be broadly similar to those that robust duties of justice require.
