I hang around on the Roman Catholic Facebook group quite a bit. The people there are nice, and most are very bright. However, I’ve seen a different side of Catholicism since I came. It seems like half of them are monarchists! They all seem to deny such basic concepts as the separation of church and state, free speech, etc etc.
My question is ultimately this: what is the Church’s philosophy towards politics? Can one be a Catholic democrat (small ‘d’)? Does the church support the criminalizing of blasphemy? Contraception? Fornication? Many of the people on there are perilously close to asking for a theocracy (or perhaps have asked for one).
The only thing that should govern your view toward politics, as a Catholic, is the teaching of the Magesterium on the subject.
The best single source for that is put out by the Pontifical Council for Justice and Peace:
The Compendium of the Social Doctrine of the Church
As to favoring a democracy versus a republic versus a monarchy versus anarchy…
A democracy is great, provided the people govern themselves by the gospel and walk in love one toward another. A democracy is a terrible thing otherwise, as the people can vote in abomination.
A representative republic is a wonderful thing, provided the representatives govern themselves by the gospel and walk in love regarding the populace they represent, and one toward another. A representative republic is a terrible thing otherwise, as the representatives can legalize abomination.
A monarchy is a wonderful thing, provided the monarch governs him/herself by the gospel and walks in love toward his subjects. A monarchy is a terrible thing if the monarch fails to live the gospel in his life, as he can create great suffering through his rule.
If all of the populace truly live by the gospel and walk in love one toward another, government is not nearly as necessary as otherwise, as the people will work together in love toward a common end: they truly need no leaders in that case. But how often will
all the people truly live by the gospel?
The bottom line is the type of government is not really terribly important, in of itself. If those who govern are ruled by the gospel and live it in their lives (his life/her life), then any form of government is perfectly OK. And without the gospel, no type of government will do the right thing by the populace.
