On Christian Doctrine

12. Accordingly the liberty that comes by Christ took those whom it found under bondage to useful signs, and who were (so to speak) near to it, and, interpreting the signs to which they were in bondage, set them free by raising them to the realities of which these were signs. And out of such were formed the churches of the saints of Israel. Those, on the other hand, whom it found in bondage to useless signs, it not only freed from their slavery to such signs, but brought to nothing and cleared out of the way all these signs themselves, so that the Gentiles were turned from the corruption of a multitude of false gods, which Scripture frequently and justly speaks of as fornication, to the worship of the One God: not that they might now fall into bondage to signs of a useful kind, but rather that they might exercise their minds in the spiritual understanding of such.
