It is, for example, a wrong action to expose oneself to death when God forbids it; but to do so is also a right action when God commands it, for all our actions are right or wrong only because God commands or prohibits them either by the eternal law, which every rational man can consult though introspection, or by the written law, exposed to the senses of sensible and camal man, who, since the sin, is not always able to consult reason.
