The freedom or immunity from coercion in matters religious which is the endowment of persons as individuals is also to be recognized as their right when they act in community. Religious communities are a requirement of the social nature both of man and of religion itself.

Provided the just demands of public order are observed, religious communities rightfully claim freedom in order that they may govern themselves according to their own norms, honor the Supreme Being in public worship, assist their members in the practice of the religious life, strengthen them by instruction, and promote institutions in which they may join together for the purpose of ordering their own lives in accordance with their religious principles.

Religious communities also have the right not to be hindered, either by legal measures or by administrative action on the part of government, in the selection, training, appointment, and transferral of their own ministers, in communicating with religious authorities and communities abroad, in erecting buildings for religious purposes, and in the acquisition and use of suitable funds or properties.

Religious communities also have the right not to be hindered in their public teaching and witness to their faith, whether by the spoken or by the written word. However, in spreading religious faith and in introducing religious practices everyone ought at all times to refrain from any manner of action which might seem to carry a hint of coercion or of a kind of persuasion that would be dishonorable or unworthy, especially when dealing with poor or uneducated people. Such a manner of action would have to be considered an abuse of one’s right and a violation of the right of others.

In addition, it comes within the meaning of religious freedom that religious communities should not be prohibited from freely undertaking to show the special value of their doctrine in what concerns the organization of society and the inspiration of the whole of human activity. Finally, the social nature of man and the very nature of religion afford the foundation of the right of men freely to hold meetings and to establish educational, cultural, charitable and social organizations, under the impulse of their own religious sense. – from Dignitatis Humanae (1965)
