“Every communication must comply with certain essential requirements and these are sincerity, honesty and truthfulness. Good intentions and a clear conscience do not thereby make a communication sound and reliable. A communication must state the truth. It must accurately reflect the situation with all its implications… 

“The process of promoting… with a view to influencing public opinion is justified only when it serves the truth and its objectives and methods accord with the dignity of man and when it promotes causes that are in the public interest… Any propaganda that deliberately misrepresents the real situation, or that distorts men’s minds with half-truths, selective reporting or serious omissions, that diminishes man’s legitimate freedom of decision, this propaganda should be rejected…

“[F]ree dialogue within the Church does no injury to her unity and solidarity. It nurtures concord and the meeting of minds by permitting the free play of the variations of public opinion… The normal flow of life and the smooth functioning of government within the Church require a steady two-way flow of information between the ecclesiastical authorities at all levels and the faithful as individuals and as organized groups.”
