1. God saw the light, that is was good, and [God] divided the light from the darkness, etc. It was said [in the preceding conference] that intellectual light (intellectualis lux) is truth, shining upon the understanding, whether human or angelic, and which shines forth inextinguishably because [the light] cannot be thought not ‘to Be’. …
As the great light it shines forth towards the comprehension of substances or essences, of worldly figures, and of natures; as the clear light it shines forth for the comprehension of rational expressions, arguments, and persuasions; as the good light it shines forth upon understanding or enlightens it towards the comprehension of propriety, activity, [and] justice; towards the comprehension of propriety with respect to [good] exercises; towards the comprehension of activity in respect to intellectual speculations; towards the comprehension of justice with respect to political laws. First, propriety must be possessed, secondly activity sought after, [and] third justice exercised.
St. Bonaventure here links the “comprehension of justice with respect to political laws” to intellectual light under the aspect of “the good light” that “enlightens [understanding] towards the comprehension of propriety, activity, and justice.” He orders this activity of comprehension by first (possess propriety), second (seek activity), and third (exercise justice). One might transpose this to a more legal key by reference to legislative, executive, and judicial powers. A closer fit, though, would be within the human person, as St. Bonaventure continues this passage:
Moreover, here is shown what kind [of person] a prelate should be, namely, being perfect in action and contemplation, he [or she] may receive the laws. Where? Upon the mountain of contemplation with Moses, so that one might act with propriety and industry, not beastly, because such are not able to ascend the mountain; for the beast that touches the mountain must be stoned.
This passage locates the human person between angel and beast. The earlier passage described the light “shining upon the understanding, whether human or angelic.” St. Bonaventure does not allude to the angelic role in the transmission of law to Moses explicitly, but that is implicit in his reference to a human person receiving the laws “[u]pon the mountain of contemplation with Moses.”
