Have We Freedom of Conscience to Profess the Syllabus?

Ven. Pope Pius IX, Syllabus of Errors
The following statements stand condemned:

Every man is free to embrace and profess that religion which, guided by the light of reason, he shall consider true.

In the present day it is no longer expedient that the Catholic religion should be held as the only religion of the State, to the exclusion of all other forms of worship.

Hence it has been wisely decided by law, in some Catholic countries, that persons coming to reside therein shall enjoy the public exercise of their own peculiar worship.

Pope Benedict XVI, Address to the Pontifical Academy of Social Sciences, May 4, 2009 (here)

The discovery of America and the ensuing anthropological debate in sixteenth- and seventeenth-century Europe led to a heightened awareness of human rights as such and of their universality (ius gentium). ...

Human rights became the reference point of a shared universal ethos – at least at the level of aspiration – for most of humankind. These rights have been ratified by almost every State in the world. The Second Vatican Council, in the Declaration Dignitatis Humanae, as well as my predecessors Paul VI and John Paul II, forcefully referred to the right to life and the right to freedom of conscience and religion as being at the centre of those rights that spring from human nature itself.
