Thou seest that this is said to a particular purpose. But unto them that are defiled and unbelieving is nothing pure. Things then are not clean or unclean from their own nature, but from the disposition of him who partakes of them. But even their mind and conscience is defiled. The swine therefore is clean.
Nothing is more unclean than a fish, inasmuch as it even feeds upon human flesh.
But it was permitted and considered clean. Yet all these were eaten. Not because they were unclean, but to check excessive luxury. They touched not the dead, and yet they were cleansed by the dead, for the victim was dead, and with that they were cleansed. This therefore was a doctrine for children.
