Those of us who believe that pro-life issues should be given priority of place in deciding how to vote are often chastised for downplaying valid concerns about the environment, foreign policy, healthcare, and other matters of morality and justice.
But as David Koyzis persuasively argues, there is something distinctive about the abortion issue:
[N]ot all issues necessarily have the same import or significance—something the language of morality may mask. In fact, there is a qualitative difference between abortion and the cluster of issues touched on above. In the case of the latter, no one disputes that the environment must be protected; the current debate revolves around how best to do so. Some favour a market-oriented approach, while others are convinced that government must play a central role. Again no one denies the desirability of furnishing the best health care to all citizens. Disagreement arises over whether this is best done through private or public insurance plans. . . .

Abortion is different. Here the quarrel is not over the best way to protect the unborn; it is precisely over whether to do so at all. Those believing women should have the right to terminate a pregnancy hold this position despite the presence of the vulnerable child. Those who believe that the unborn deserve protection do so because of the child’s presence. This fundamental disagreement over what is at stake is what sets the abortion issue apart from most others. Proponents of the so-called consistent life ethic generally fail to comprehend this. Such bishops as Denver’s Charles Chaput are right to make a fuss over Catholic politicians who support abortion rights. Abortion is not merely a private opinion; it is a clear matter of justice that needs to be addressed head on.
