Many people point to Luke 1:41 (“When Elizabeth heard Mary’s greeting, the child leaped in her womb.”) as evidence that, in the view of the Bible, a fetus is a child. But these people have misinterpreted the verse.
On one hand, the reasoning behind the flawed claim is straightforward: If it was a “child” that leaped while still in Elizabeth’s womb, whatever is in a womb must be a child. So a fetus is a child. And, in turn, abortion must be the same a killing a child. But though straightforward, this reasoning is misguided.
Language commonly disassociates a word from the time at which it applies. For instance, in Genesis 25:23, God tells Rebekah that “two nations are in your womb.” Surely this doesn’t mean that a fetus is a nation (and that, therefore, a single abortion is identical to genocide). Rather, the “two nations” are “two future nations.”
Similarly — as I explain in my Huffington Post piece, “What Does the Bible Really Say About Abortion?” — this is why in English a drawing of George Washington at age two might be captioned “The Founding Father as a Child” even though he wasn’t yet the founding father. And it’s the reason a mother might say that her motivation to get married and have children was that she pictured her life with her children and liked what she saw. “Her children” here — like “the founding father” and the “two nations” — represent the future. This is also why we might talk about “Mark Twain as a young child,” even though he wasn’t Mark Twain yet, not having yet assumed that pen name.
It might perhaps be clearer in all of these cases to specify the time. So, “the future Mark Twain as a young child,” a woman’s “future children,” or “the future founding father,” but language doesn’t require it. In just the same say, the Bible doesn’t need to specify “two future nations are in your womb” or “Elizabeth’s future child leaped in her womb.”
People are generally able to recognize this linguistic pattern, but when it comes to abortion and the status of a fetus, people are sometimes driven to read more into the text than was originally there.
So while Luke 1:41 is consistent with a fetus being a child, it is equally consistent with a fetus not being a child. Luke 1:41 does not tell us anything about the status of a fetus, so it doesn’t tell us anything about abortion.
