John Paul II says in the encyclical Sollicitudo rei socialis (December 30, 1987):
“The Church does not propose economic and political systems or programs nor does she show preference for one or another, provided that human dignity is properly respected and promoted, and provided she herself is allowed the room she needs to exercise her ministry in the world.”
In the encyclical Centesimus annus (May 1, 1991), John Paul II states:
“The Church respects the legitimate autonomy of the democratic order and is not entitled to express preferences for this or that institutional or constitutional solution. Her contribution to the political order is precisely her vision of the dignity of the person revealed in all its fullness in the mystery of the Incarnate Word.”
