What has been will be again, what has been done will be done again; there is nothing new under the sun. – Ecclesiastes 1:9 (NIV)
Abortion has been the scourge of the human race for thousands of years. The famed Hippocratic Oath committed the doctors who swore by it to ομοιωs δε ουδε γυναικι πεσσον Φθοριον δωσω generally translated as "not give to a woman a pessary to cause abortion"). That oath goes back to the 4th century B.C.
With every generation comes a new era of sexual exploration and discovery. One might think (or hope) that what was gleaned by an earlier generation would be enough to satisfy those coming later. But that is not the case. And so each generation experiments, exploiting others in its quest for sexual knowledge and satisfaction. The result of this is, even as it has been since the time of Hippocrates, some unwanted pregnancies. One might use the language "unplanned" (as opposed to unwanted) pregnancies, but there is ample knowledge among the vast majority of humans to understand how a pregnancy occurs.
So a sexual encounter can result in an unwanted pregnancy and what is one then to do? There is no such thing as going back in time. As with all of life we cannot undo our actions or what some might call our "mistakes." And so with the pregnancy, the attention immediately turns from passion to practicality. In either case what was or is central are the two who engaged in the sexual act. What made them feel good now turns to what makes them feel encumbered, or fettered. A baby will only mess up their plans. It has always been only about them and never about the baby.
It is difficult to imagine this ever changing for each generation feels this urge, this need, to sexually explore just as did the previous generations. The only real difference now is that the cultural taboos that were formerly held (that put the parameter of marriage over the exploration) have all but been removed. The result of this has not been good for the mortality rates of the unborn.
If our society is bent on "going to hell in a handbasket" there isn't a lot that we can do to stop it. Legislation may slow it down, but it won't stop it. Yes, Christians are to be salt and light…aiding our world and helping direct it. The church offers life and light to those who come into it, but to a society that is uninterested in the message of the church, our salt will be pretty much left in the shaker while the shades will be pulled down to keep our light out.
This is not a good state of affairs. Maybe it will someday change. But that is how things are in America in 2020.
