Do we have a duty to help the poor? How do we quantify that?

[Crusading Philologist]

OK.  Where I was actually going with this is - if we have a duty to help the poor, does that then translate into a right to that help for the poor?  In other words, does a poor person have the right to have his basic material needs met by someone else?

At first glance, I wouldn't think so. Charity goes beyond justice. We are called to be charitable to all people, but people are not actually owed charity.
