Cyril of Alexandria, on Prov 27:23

“Be diligent to know the countenance of thy cattle, and consider thy own flocks:”

“It is not fitting to address simply to all who have believed in Christ instruction upon all points, for it is written, "With knowledge learn the souls of your flock." For the way is very different by which we establish in the paths of truth one who has but just now become a disciple, from one more confirmed in mind and able to understand what is the height and depth, and what the length and breadth. In the former, use simple teaching, in which there is nothing profound or difficult to understand. Counsel him to escape from the error of polytheism and fittingly persuade him to discern by the beauty of things created, the universal creator and artificer, who is one by nature and truly God.”
