Ambrose of Milan

In the pine cone nature seems to express an image of itself. It preserves its peculiar properties which it received from that divine and celestial command, and it repeats in the succession and order of the years its generation until the end of time is fulfilled.

The Word of God permeates every creature in the constitution of the world. Hence, as God had ordained, all kinds of living creatures were quickly produced from the earth. In compliance with a fixed law they all succeed each other from age to age according to their aspect and kind. The lion generates a lion; the tiger, a tiger; the ox, an ox; the swan, a swan; and the eagle, an eagle. What was once enjoined became in nature a habit for all time. Hence the earth has not ceased to offer the homage of its service. The original species of living creatures is reproduced for future ages by successive generations of its kind.
