Tell you what. Put your money where your mouth is.
Run for office on the platform that society needs to be Catholic.
Let us know how you do.
I'm way ahead of you.
Here's my campaign slogan:
Vote Monarchist. Make your last vote count.
Bwahahaha! lol.
If the conflict is between Church and Constitution, then it is Constitution that must be compromised, for the Church cannot.
As for running for office: democracy is a creature of the atheistic Revolution, not the Kingdom of God. Popular government supposes that man is wise enough to make his own laws, including the laws of morality. In a people's state, vox populi is vox Dei. This idea, which is as old as the Serpent himself ("Ye shall be as gods, knowing good and evil...") is antichristian, anti-life, and antihuman.
The Revolutionary ideas of voting, popular sovereignty, and the libertarian "do as thou wilt" are pagan, heretical and foreign to Christianity. Our Lord is not the President of the Republic of Heaven. He is King of the Universe. The social structures we live under should flow from this Divine structure, not contradict it. Popular government is a fist shaken in the face of authority, including God, the ultimate Authority; it is the cry of Lucifer, a political "non serviam" from the pit of Hell. As such, it is doomed to fail, sooner or later - and when authority is restored, it won't be pleasant. The Lord sends rain upon the just and the unjust, I'm afraid.
