In a recent message to the World Medical Association, Pope Francis confirmed his support (and that of Catholic doctrine) for principles of medical futility, non-beneficial treatment, and therapeutic obstinacy.
“The growing therapeutic capabilities of medical science . . . have become ever more effective, but they are not always beneficial: they can sustain, or even replace, failing vital functions, but that is not the same as promoting health.”
“Greater wisdom is called for today, because of the temptation to insist on treatments that have powerful effects on the body, yet at times do not serve the integral good of the person.”
