In Christian terms there is no differentiation between the born and unborn. Both are afforded equal protection under the statement given in Exoddus 21. Though there has been some controversy about the interpretation of this passage, many agree that its meaning is: "When men strive together and they hurt unintentionally a woman with child, and her child comes forth but no mischief happens, that is, the woman and the child do not die, the one who hurt her shall surely be punished by a fine. But if any mischief happens, that is, if the woman dies or the child, then you shall give life for life.".
From this passage, God makes no legal distinction between a person born and one not yet born. Both are of equal value to God. Therefore it could be argued that every child has a right to life from a Christian perspective. Clearly this is a very vague and weak argument when deciding upon abortions, it has no real "backbone". The issue of abortion on a legal basis should purely not be concerned with what the Bible says or the discoveries made by fetologists. Surely the argument is based on what is the ethical decision. Of course this is very broad and vague subject and presents itself with many problems instantaneously. For example, how can something "ethical" be called universal if we consider cultural relativism and the different people all with their own views and religions. Any generalized statement made about whether a child has a right to life would have limited value in a given situation. Personally I believe situation ethics to be one of the best solutions to this ethical problem. Although it could be argued that situation ethics is generalized in itself because it has not got an answer for everything, however I believe that if it is used in conjunction with other theories and views, it could be effective and help lead to the "right" decision. For example, a fourteen year old girl suffering from a severe brain tumor and is suffering immense pain and there is clearly no way of curing her condition or even improving it, her future is likely to be unbearable.
