To suggest that the Bible is silent on abortion is a lie.  In both the Old and New Testaments, the language used to describe born and unborn people is the same.  For example, in Luke 1:41, the unborn John the Baptist is called a “brephos” which means “babe” or “baby” in Greek.  Then, in the very next chapter, the born Jesus is also called a “brephos.”  We are also told that Elizabeth’s baby leapt in her womb upon being in the presence of Mary.  Should we conclude that this makes no statement about the unborn?  If so, and if the Bible is silent on abortion, then it is logical to also conclude that Scripture is indifferent about whether these women would have aborted Jesus and John the Baptist.  After all, by pro-choice reasoning, at this point they didn’t even exist.  (A few Scriptural references to the unborn include: Genesis 25:22-24; Job 31:15; Psalm 22:9-10; Psalm 139:13-16; Jeremiah 1:5; Hosea 12:2-3; Luke 1:15; Luke 1:41; and Exodus 21:22-24.)

Moreover, not every word Jesus uttered is recorded in Scripture so there is no way to know whether He ever addressed abortion or not.  We should also remember that there is no record of Jesus ever speaking out against slavery – a point which apologists for slavery routinely made.  In fact, most of our laws relate to behaviors which neither Jesus nor the Bible specifically addressed.
