Tertullian

“ At the same time, with respect to the order of development in Wisdom, I have admitted [11] that it flows from simplicity. In brief, “the dove” has usually served to figure Christ; “the serpent,” to tempt Him. The one even from the first has been the harbinger of divine peace; the other from the beginning has been the despoiler of the divine image. Accordingly, simplicity alone [12] will be more easily able to know and to declare God, whereas wisdom alone will rather do Him violence, [13] and betray Him. ”

“ They were neither children nor infants; in other words, they were not simple. The apostle, too, bids us to “become children again” towards God, [9] “to be as children in malice” by our simplicity, yet as being also “wise in our practical faculties.” ”
