Man always travels along precipices... His truest obligation is to keep his balance.
Pope John Paul IICondemning 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.
Pope John Paul IIMuch 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
