“By its interventions in this area, the Church’s Magisterium does not
wish to exercise political power or eliminate the freedom of opinion of
Catholics regarding contingent questions. Instead, it intends – as is
its proper function – to instruct and illuminate the consciences of the
faithful, particularly those involved in political life, so that their actions
may always serve the integral promotion of the human person and the
common good. The social doctrine of the Church is not an intrusion into
the government of individual countries. It is a question of the lay Catholic’s
duty to be morally coherent, found within one’s conscience, which is one
and indivisible. ’There cannot be two parallel lives in their existence: on the
one hand, the so-called ‘spiritual life’, with its values and demands; and on
the other, the so-called ‘secular’ life, that is, life in a family, at work, in social
responsibilities, in the responsibilities of public life and in culture.’ [emphasis
added]
“The branch, engrafted to the vine which is Christ, bears its fruit in every sphere
of existence and activity. In fact, every area of the lay faithful’s lives, as different
as they are, enters into the plan of God, who desires that these very areas be
the ‘places in time’ where the love of Christ is revealed and realized for both the
glory of the Father and service of others. Every activity, every situation, every
precise responsibility – as, for example, skill and solidarity in work, love and
dedication in the family and the education of children, service to society and
public life and the promotion of truth in the area of culture – are the occasions
ordained by providence for a ‘continuous exercise of faith, hope and charity’
conscience on questions of politics is not slavish acceptance of positions alien
to politics or some kind of confessionalism, but rather the way in which Christians
offer their concrete contribution so that, through political life, society will become
more just and more consistent with the dignity of the human person.”
