If the Declaration of Independence states our creed, there can be no right to abortion, since it means denying the most fundamental right of all, to human offspring in the womb. The Declaration states plainly that we are all created equal, endowed by our Creator with our human rights.
But if human beings can decide who is human and who is not, the doctrine of God-given rights is utterly corrupted. Abortion is the unjust taking of a human life and a breach of the fundamental principles of our public moral creed.
Some people talk about "viability" as a test to determine which offspring have rights that we must respect, and which do not. But might does not make right. And so the mere fact that the individual in the womb is wholly in its mother's physical power and completely dependent upon her for sustenance gives her no right whatsoever with respect to its life, since the mere possession of physical power can never confer such a right. Medical procedures resulting in the death of an unborn child, except as a collateral and unintended consequence of efforts to save the mother's physical life, are therefore impermissible.
As for the 'so-called right to suicide' and related practices, such as euthanasia, whatever emotional arguments we make on their behalf, they represent a violation of the principles of the Declaration of Independence. Our rights, including the right to life, are unalienable. If we kill ourselves or consent to allow another to do so, we both destroy and surrender our life. We act unjustly. We usurp the authority that belongs solely to the Creator, and deny the basis of our claim to human rights.
