39. All forms of missionary activity are marked by an awareness that one is furthering human freedom by proclaiming Jesus Christ. The Church must be faithful to Christ, whose body she is, and whose mission she continues. She must necessarily "go the same road that Christ went-namely a road of poverty, obedience, service and self-sacrifice even unto death, from which he emerged a victor through his resurrection."63 The Church is thus obliged to do everything possible to carry out her mission in the world and to reach all peoples. And she has the right to do this, a right given her by God for the accomplishment of his plan. Religious freedom, which is still at times limited or restricted, remains the premise and guarantee of all the freedoms that ensure the common good of individuals and peoples. It is to be hoped that authentic religious freedom will be granted to all people everywhere. The Church strives for this in all countries, especially in those with a Catholic majority, where she has greater influence. But it is not a question of the religion of the majority or the minority, but of an inalienable right of each and every human person.

On her part. the Church addresses people with full respect for their freedom.⁶⁴ Her mission does not restrict freedom but rather promotes it. The Church proposes; she imposes nothing. She respects individuals and cultures, and she honors the sanctuary of conscience. To those who for various reasons oppose missionary activity, the Church repeats: Open the doors to Christ!

Here I wish to address all the particular churches, both young and old. The world is steadily growing more united, and the gospel spirit must lead us to overcome cultural and nationalistic barriers, avoiding all isolationism. Pope Benedict XV already cautioned the missionaries of his time lest they "forget their proper dignity and think more of their earthly homeland than of their heavenly one."⁶⁵ This same advice is valid today for the particular churches: Open the doors to missionaries, for "each individual church that would voluntarily cut itself off from the universal Church would lose its relationship to God's plan and would be impoverished in its ecclesial mission."⁶⁶
