Whether or not health care is perceived as a right in any particular country is fluid over time.  The US is moving in that direction, long since achieved by all other western democracies. IMHO, critically important in that movement is the disposition of medical professionals, and I sense that that group of stakeholders is pretty close to regarding health care as a right. Indeed, the only stakeholder holdouts would appear to be insurance companies whose ox will be fully gored when the US finally buys into single payer. And of course political ideologues, who value the notion of capitalism more than the common good established by hard evidence. 

As for the Christian attitude, other have cited chapter and verse for you re the official Catholic position. What I find so very interesting is that conservative Catholics who insist on voting according to Catholic morality re abortion, with equal fervour vote against the magisterium on heath care. Can you explain that to me?
