After Vatican Council II, one of the criticisms launched against the council by “traditionalists” is its approach toward non-Christian religions. Nostra Aetate proclaimed the need for Christians to look to other religious traditions, and to promote the good within them:
The Church, therefore, exhorts her sons, that through dialogue and collaboration with the followers of other religions, carried out with prudence and love and in witness to the Christian faith and life, they recognize, preserve and promote the good things, spiritual and moral, as well as the socio-cultural values found among these men. (Nostra Aetate 2).
God has been at work in and through the world, and people have responded to him. Of course, their understanding might have been crude, or it might have been corrupted through centuries of misunderstanding, but that does not remove the positive value of their experience with God and how it has influenced them and their understanding of holiness. “From ancient times down to the present, there is found among various peoples a certain perception of that hidden power which hovers over the course of things and over the events of human history; at times some indeed have come to the recognition of a Supreme Being, or even of a Father” (Nostra Aetate 2).
Respect for the positive good in world religions is respect for God. Even if non-Christians worship false gods, their desire for worship is proper and to be respected, so much so, if they blaspheme what they believe to be God, they are sinning. Indeed, in Leviticus, we find Scripture making this point: “And say to the people of Israel, Whoever curses his God shall bear his sin” (Lev.24: 15). We must remember that the Law not only directed how Israelites should act, but also explained the kind of conduct Israelites should expect of non-Israelites who dwell with them. The verse speaks about the sin of whoever curses “his God,” which means, whoever curses that which they think to be God. Theodoret of Cyrus puts it this way:
In setting down the law of blasphemy, he used the word ‘God’ to refer also to what is falsely called ‘God.’ He said that he who reviles a false god commits a sin, but he did not judge him worthy of punishment. It is not the man of right belief who commits sin when he blasphemes a false god, but the one who believes in it and reviles it, for he blasphemes what he reverences. So he called such a sin blasphemy, not because of the innate worth of what is blasphemed, but because of the belief of the one who commits the blasphemy, for he blasphemes the god, not as a false god, but as through it were the true God.
 They claim to be following tradition, but they are very selective in which traditions they follow.
