An example of an issue not specifically addressed in Scripture is abortion. How does biblical teaching apply to the abortion debate? Two passages (Exo. 21:22-25 & Luke 1:41-44) seem to suggest that an unborn baby should be considered a person at least by the time of quickening (cf. Psa. 139:13-16). Perhaps Exo. 20:13 can be understood as implying, “Thou shalt not murder thy baby”. However, because believers do not dictate government policies, they need to share logical as well as biblical reasons for not aborting babies.
Logically, the crucial question is this: “When does a developing fetus become a human person with the God-given right to civil life so that to kill it is murder and warrants punishment?” Considerations other than the advent of personhood are irrelevant, unless someone would use the same rationale to justify the killing of children and adults. As a person considers two pictures: one of a seven-month-old fetus in the womb, and one of a seven-month-old preemie outside the womb, he/she should understand that location and mode of breathing is not a valid basis for defining personhood.
Those who view conception to be the criterion of personhood should mourn miscarriages in the same way they would death of post-birth babies, but there is logical reason to consider personhood beginning the same way doctors use to consider a person to be dead: brain death or the absence of certain brain wave activity detected by an electroencephalogram (EEG). We might call this stage “sentience”, when the fetus has brain life of the type detectable in a person deemed to be alive and to have the civil right to life.
Thus, everyone should agree that the fetus becomes sentient and a legal person at least by that stage of development. In the absence of definitive Scriptural teaching, this is only a partial solution, but it is better than allowing abortion throughout pregnancy. It recognizes that people may reasonably disagree about the status of the fetus between conception and sentience. Implementing this solution requires educating people about fetal development until society develops a consensus that when a fetus becomes sentient, abortion is a type of manslaughter or murder and should be punished appropriately.
