The Catholic politician's duty is not to vote for legislation that merely appeases the majority, especially if a majority of the population holds to positions that are racist, antihuman and are inherently illogical. The duty of the Catholic public servant is to promote laws and policies that are true and good, and to vote against laws and policies which are evil, e.g., legislation which destroys unborn life, promotes violence and/or promotes immorality. For example, the slogan "personally opposed to abortion" is a hollow verbal and mental gymnastic which avoids the implications of the Catholic Faith handed on to us by the Apostles and neglects to consider the consequences of promoting unjust laws. Catholics have a duty to shape legislation and policy so that laws conform to the natural law, which is itself a mirror of the divine Law.
The Church's social doctrine is the only body of thought that is capable of supporting authentic democracy and its increase. The Constitution of the United States, magnificent document that it is, will not be respected nor authentically interpreted unless politicians are oriented to the mindset which produced the documents in the first place. That is, a Judeo-Christian ethos. The Catholic Church's expression of that Judeo-Christian heritage is the clearest and most thorough presentation of that heritage. The Church's teaching produces better citizens than atheistic secular philosophies. One need only take note of the stark contrast between societies which have embraced a militant secularism in the past, e.g., the former Soviet Union and currently North Korea (DPRK), and western societies that value fundamental freedoms but which, forced to embrace the ideologies imposed by militant secularists, are beginning to collapse. Look at Britain and most, if not all, of the Scandinavian countries.
- Immigration and social(ist) policies are failing, ghettos are emerging and immigrants are engaging in violence to impose a radical islamist ideology on states that have opened their doors to suffering peoples.
- Those same suffering peoples, i.e., people who suffered in their former Middle-eastern and African homelands, are now inflicting suffering on the western societies which have offered refuge.
- The states which have welcomed immigrants from warring states have provided comprehensive welfare and free medical and educational support.
- The welcoming states are now rife with immigrant violence: e.g., a huge increase in rape of Swedish women; violent demonstrations seeking the imposition of shari'a law while flouting the law of the land; destruction of property; exclusion of indigenous populations from muslim dominated communities; and so forth.
Democracy, a true and lasting democracy that protects the weak and shelters the homeless and educates its citizens because it is not only practical but morally right to do so, depends on people who are themselves virtuous and know how to promote the common good. Virtuous people, guardians of democracy, work to root out corruption when evil infects government and law enforcement.
