The Holy See hasn't forgotten the lesson, and I have no reason to believe that they ever will.If we do not learn from the past, we are doomed to repeat it.
It's a lesson the world should NEVER FORGET..
Nobody may be forced to act against his convictions, nor is anyone to be restrained from acting in accordance with his conscience in religious matters in private or in public, alone or in association with others, within due limits. This right is based on the very nature of the human person, whose dignity enables him freely to assent to the divine truth which transcends the temporal order. For this reason it continues to exist even in those who do not live up to their obligation of seeking the truth and adhering to it.
If because of the circumstances of a particular people special civil recognition is given to one religious community in the constitutional organization of a state, the right of all citizens and religious communities to religious freedom must be recognized and respected as well.
The right to religious liberty is neither a moral license to adhere to error, nor a supposed right to error, but rather a natural right of the human person to civil liberty, i.e., immunity, within just limits, from external constraint in religious matters by political authorities. This natural right ought to be acknowledged in the juridical order of society in such a way that it constitutes a civil right.
