This is from Divine Providence, n. 136:2 (emphasis added):
The external cannot compel the internal, but the internal can compel the external. Who can be compelled to believe and to love? One can no more be compelled to believe than to think that a thing is so when he thinks that it is not so; and one can no more be compelled to love than to will what he does not will, for belief belongs to the thought and love to the will. There is, however, an internal which may be restrained by the external from speaking ill against the laws of the kingdom, the moralities of life and the sanctities of the Church. To this extent the internal may be compelled by threats and punishments; and it, moreover, is compelled and ought to be. This internal, however, is not the human internal that is properly so-called: it is an internal that man has in common with beasts; and beasts can be compelled. The human internal has its seat above this animal internal; and it is the human internal that is here meant, and it cannot be compelled.
So, should we have laws against speaking against the U.S. law, morality, and religion? I’m not sure – I’m just putting this out there to hear what other people have to say.
