"Politico-religious wanderings?!"
First I must respond to this issue before I address the evil of abortion.

Unfortunately, many Americans think that the First Amendment says "Separation of Church and State". 69% of them believe that the First Amendment says "Separation of Church and State". Yet, these words do not appear in the First Amendment or anywhere else in the Constitution.

The First Amendment says:
"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances". The First Amendment gives citizens the Freedom to Worship God without Government interference. The statement of " Separation of Church and State" (which Thomas Jefferson used in his letter) simply means (and he emphasized this emphatically) that religion cannot be imposed by the state but can only be accepted in liberty. The Founding Fathers did not attempt to destroy or deface the work of Divine Providence but accepted it, and went on to organize the government in harmony with the Real Divine Order. They were inspired by reality, not by theory or speculation. In fact, they believed that the people are not the source of political authority but rather the medium by which it is expressed. Authority emanates not from the people but from God. If divine authority is dismissed, the scaffolding on which civil authority rests is obliterated and can sustain itself only by brute force. The connecting link between God and people is the natural law, which is transmitted through two channels: reason (purified by the light of faith) and divine revelation. Everything depends on God, including progress. The goal is to harmonize Church and State, religion and politics by comforming both to the Reality of the Divine Order. Modern liberalism is destructive insofar as it endeavors to separate the progress of society from religion. This is called "political atheism, for power is emancipated from all restraints, and thus everything is reduced to less than "low average" since popular and false opinions are substituted for Changeless Divine Truths. For these (and other reasons) G.K Chesterton reasserted that Church, which is divinely founded is "more immortally important than the State".

Read the Constitution and ponder... for it also speaks of the fundamental right to life. And, it is not possible to speak of the right to choose when a clear moral evil is involved, when what is at stake is the commandment "Do not kill!"
