45 "If a brother or a sister be naked and in want of daily food," says St. James, "and one of you say to them, 'Go in peace, be warm and filled,' yet you do not give them what is necessary for the body, what does it profit?" (48) Today no one can be unaware of the fact that on some continents countless men and women are ravished by hunger and countless children are undernourished. Many children die at an early age; many more of them find their physical and mental growth retarded. Thus whole populations are immersed in pitiable circumstances and lose heart.
