Because politics, in the vision of the Church, deals with the good of people, individually and collectively, the primary subject of the political system is the human person. As a result, there are matters and issues that arise which the Church considers fundamentally
related to the dignity of the human person.
These matters are life, the family, education, religious belief, justice and protection for those most in need in society. The Church’s approach to such issues is based above all in the very nature of the human person as created in the image and likeness of God.
Consequently, you can certainly understand why the Church takes such an interest in these questions. It does so, not in an attempt to impose its views or doctrines on society, and even less on any legislative body, but rather it does so in a spirit of service to the common good and the nature of the human person, realities which transcend institutions, but which must rely on the good intentions of institutions to be protected and safeguarded. In that context it is even foreseen that at times the Church can offer its own expertise on these universal questions in collaboration with public authorities while always respecting the distinct competencies that each has.
Obviously, I am very much aware of the challenges facing you as lawmakers, in a pluralistic society, which has so many voices and different points of view about a whole range of issues. Yet, a convergence can be found in keeping in mind those principles whose goal you have as legislators in a spirit of service to your country: to promote the common good and to respect the nature and dignity of the human person.
That is how to do it. Always praise politicians for being public servants, talk up this vocation and thank them for taking on such an onerous responsibility.
