Private property
The Church has a role in discussing these issues. Social and economic issues are vital to her not from a technical point of view but in terms of moral and ethical issues involved. Ethical considerations include the nature of private property concerning which, within the Catholic Church, several conflicting views had developed. Pius XI proclaims private property to be essential for the development and freedom of the individual. Those who deny private property deny personal freedom and development. But, says Pius, private property has a social function as well. Private property loses its morality if it is not subordinated to the common good. Therefore, governments have a right to pursue redistribution policies. In extreme cases, the Pope recognizes that the State has a right to expropriate private property.
