There are six different Greek words that Christ used that could be translated a "child" or "children." The purpose of this article is to explain the difference between them. It doesn't analyze Christ's view of children itself, but below, you will see all the references Christ makes to children (though not to "son"), so you can make your own judgment. Two other words, the Greek word for "fruit" and "seed" also can have the metaphorical meaning "offspring" in the sense of "Abraham's seed," and Christ uses them that way, but not really "children" so they are not covered here. these words are used frequently but almost always to mean, well, fruit and seeds.
Note: Jesus separated himself from tradition Judaism by his interest in children. From the title he gave to himself to dozens of different quote, Jesus spoke of the value of childhood. However, in the entire Old Testament I have only found less than thirty verses referring to children. Jesus discussing children in dozens of verses, starting with the fact that he defines God as the Father.
The Son as the Child
The most common, Greek word is but far, that be translated as "child" is υἱὸς (huios). It means a "son," and more generally, a "child." It is used over a hundred times, most often, however, in references to the "Son of Man" and "Son of God." Those two phrases are analyzed in this article.
This word refers to a "child" in the sense of an offspring, but it is used to refer to primarily to adult children, not the young. Of course, since most of these references are to Christ himself, at least as a symbol, this is obvious.
While it can be translated as "child" and could easily be translated that way in the two titles Christ uses to refer to himself, we can categorize this word as used primarily to refer to a son as a son, a male child and heir to a house. For example, in John 8:35, Christ says a slave doesn't stay in the house forever, but the son does. Here, the sense is that the son inherit the house after the father dies.
However, this word is not used to refer to children generally, but specifically to male children because of their position as men, that is, workers and householders.
The Child as Son
The next most common word is used a couple of dozen times (26), but it means "child" and "children" more generally. However, strangely enough, it is sometimes translated as "son" as well, as least in the KJV. This word is τέκνοις (teknon). It means "that which is born," "child," and "the young."
This is the word that Christ uses most commonly to refer to children general as children, that is, as offspring of either sex. However, If you look at the references, below, this word is translated in the plural as "children" but when it is used to one or two children, it is translated as "son" or "sons." This is especially noticeable when the word is used in address a character in a parable.
Again, this word doesn't refer to children as the young, but again, more generally as offspring. As you will note, this is the word Christ uses to refer to the "children" of Abraham and Israel.
Note the last use referred to below (scroll down to the References to Teknon section), is a slightly different form, teknion, which Christ uses to refer to his disciples. This version was used by teachers to refer to their students.
Children as the Young
Finally, we come to the word Christ uses to refer to children as the "young." This word is paidon. which means "little child" or "young child," "infant" or "young slave." It is use a little over a dozen times (14).
Childhood, however, in Christ's time was a far shorter period of time than it is today. Generally, this word refers to those up to about seven or eight years old. So the sense is young children. This is the age where children were considered entirely dependent. After this age, they were considered productive, perhaps even productive enough to survive by their own labor at least as a servant. Of course, childhood today, in the sense of being dependent, can last a lifetime.
When Christ teaches lessons regarding becoming like a child, this is the word he uses. When he discusses how to treat children, this is the word he uses.
However, note that the last reference on the list is actually a call to the apostles when they were fishing and didn't recognize him. This is a great example of Christ having a little fun.
Children as the Little Ones
Next, we have a word that doesn't mean "child" exactly, but it is used by Christ somewhat interchangeably with paidion above, with Christ often alternating between the two terms. This word is mikros. It is an adjective that means "small," "little," and "young."
What makes this word interesting is that Christ uses it for his plays on words. Note on two occasions (Mat 11:11, Luke 9:48) he uses it in verses referring to children, but it gets translated as "least" as in, the "least in heaven." This seems likely that these references are a bit of fun Christ is having with the world.
Note that most of the references to "little ones" focuses on their vulnerability. Christ uses it to emphasis their size and dependence on adults. As opposed to those big kids, over seven, who can take care of themselves.
Children as Babies
The fifth word translated as "children" or "babies" is nepios. this word means "infant," "child," "minor" of children up to puberty, "infancy," "the young" of an animal, of the understanding "childish," "silly," and of bodily strength, "like that of a child."
Christ uses this word only twice.
In the first use, Christ seems to use this term for its sense of "childish" and "silly" because he is using it to describe himself (Mat11:25). Its second use, Matthew 21:16, is a quote from the Septuagint.
Children Yet to Be Born
Finally, we have the term that is translated as "child" that Jesus uses to refer to babies who are yet to be born. This term is gaster, (γαστρὶ), which doesn't mean "child" at all. It means "paunch," "belly," "gluttony." Wth the verb "to have" and the preposition "in," the concept is to "have in the belly," which usually means "big with child."
Jesus uses this term in three verses , which are all different versions of the same saying referring to pregnant women.
