Clement of Alexandria
Patristic
c. A.D. 150–215
“Then it is right to notice, with respect to the appellation of infant (νήπιον), that it is not predicated of the silly: and νήπιος is νεήπιος (since he that is tender-hearted is called ἤπιος), as being one that has newly become gentle and meek in conduct. This the blessed Paul most clearly pointed out when he said, "When we might have been burdensome as the apostles of Christ, we were gentle (ἤπιοι) among you, as a nurse cherisheth her children." The child (νήπιος) is therefore gentle (ἤπιος), and therefore more tender, delicate, and simple, guileless, and destitute of hypocrisy, straightforward and upright in mind, which is the basis of simplicity and truth. For He says, "Upon whom shall I look, but upon him who is gentle and quiet?" For such is the virgin speech, tender, and free of fraud; whence also a virgin is wont to be called "a tender bride," and a child "tender-hearted." And we are tender who are pliant to the power of persuasion, and are easily drawn to goodness, and are mild, and free of the stain of malice and perverseness, for the ancient race was perverse and hard-hearted; but the band of infants, the new people which we are, is delicate as a child.”
