So we are in agreement. As long as one agrees that the ideal is a society of 100% Catholics, they can find it prudent at the present time to tolerate religious freedom
1.) The ideal society is that all are Catholic.
2.) After that, the ideal is that the State function as a Catholic State and frame its laws in accord with the laws of God and the Church, which means forbidding false religions, even if there are some non-Catholics lving there.
3.) The next level down would be for the state to merely tolerate false religions in order to prevent a civil unrest.
4.) After that, the next level down would be a pluralistic society such as America, where all religions - true and false - are placed on an equal footing.
5.) The next level down from there would be a society where Christianity is forbidden. In this case, Christians would be permitted by God to practice their faith based on the religious liberty that they possess from God, since they belong to His true relition. They state might kill them for it, but they do have the right from God to practice their religion.
… and even protect it in constitutions
This is where we start to get into the problems. Pluralistic society is not the idea, and to say that the constitution SHOULD protect religious liberty is to say that the State should be pluralistic. This would mean a Catholic State that forids false religions would be bad. Yet, as we know, the ideal is that the State profess the true religion and frame its laws according to that religion. That way, the laws of the State help direct man to his proper end. That is the ideal. It doesn’t mean the Church absolutely condemns other forms of society, but it must be affirmed that these are deviations from the ideal.
Where the problem comes in is that, according to the modern idea of religious liberty, the “ideal” (the Catholic State that forbids false religions) is unjust. Why? Because the modern understanding of religious liberty is that each man has
“the right to embrace and profess that religions which, guided by the light of reason, he shall consider true”. (Syllabus #15) They erroneously believe that this is a God-given right of nature. What does that mean for the Catholic State that forbids false religions? It means that this “ideal” State is a violation of a “right of man” - the pretended “right” to practice a false religion.
One of the means by which Liberalism accomplishes its revolution is by ascribing “rights” to man that man does not possess. Just as it pretends that women have a “right to choose”, so too it pretend that man has a “right to religious liberty”. How do we know that a women does not possess an inherent right to choose to have an abortion? Because it violates the 5th commandment, and no one has a right to violate God’s law. And how do we know that man does not possess an inherent “right to religious liberty”. Because it violates God’s “first and greatest” commandment.
The modern understanding of religious liberty is false,because it claims that man has a right to profess a false religion. It is based on a false right, just like the pro-abortion movement.
Yet, based on the erroneous modern understanding of religious liberty, Rome itself has forced Catholics states to change their constitution in such a way that the profession of the Catholic religion as the only religion of the State was dropped. Rome itself forced this change. Why? Because of Vatican II.
According to Rome, Vatican II taught that the ideal state is a violation of a “right” of man. This is a serious error and implicitly condemns 1500 years of Catholic teaching and practice. It condemns all of Christendom, in which Catholicism was the sole religion of the State “to the exclusion of all other forms of worship” (Syllabus #77)
