Much of the violence that humanity suffers in our times is rooted inmisunderstanding as well as in the rejection of the values and identityof foreign cultures. Tourism improves relationships between individualsand peoples; when they are cordial, respectful, and based on solidarity theyconstitute, as it were, an open door to peace and harmonious coexistence
Condemning class struggle does not mean condemning every possible form of social conflict. Such conflicts inevitably arise and Christians must often take a position in the "struggle for social justice." What is condemned is "total war," which has no respect for the dignity of others (and consequently of oneself). It excludes reasonable compromise, does not pursue the common good but the good of a group, and sets out to destroy whatever stands in its way.
True freedom is not advanced in the permissive society, which confuses freedom with license to do anything whatever and which in the name of freedom proclaims a kind of general amorality. It is a caricature of freedom to claim that people are free to organize their lives with no reference to moral values, and to say that society does not have to ensure the protection and advancement of ethical values. Such an attitude is destructive of freedom and peace.
