To restore America's moral leadership role in the world:
"Most blessed Virgin Mother vouchsafe.
We beseech thee, accept the decree of Holy Mother Church placing our beloved country under the protection of thy Immaculate Conception.
Accord it thy continuous care and powerful influence that God may safeguard it from all danger and permit it to fulfill its high mission among the peoples of the earth."
George L Duval December 8th 1917
To defend Americans from mandates that violate the Constitution:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press, or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
The first Amendment to the Constitution -- December 15, 1791
To restore the rights upon which America was founded:
"The sacred rights of mankind are not to be rummaged for, among old parchments, or musty records. They are written, as with a sun beam in the whole volume of human nature, by the hand of the divinity itself; and can never be erased or obscured by mortal power.''
Alexander Hamilton, 1775
"WE hold these Truths to be self-evident, that all Men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the Pursuit of Happiness--That to secure these Rights, Governments are instituted among Men, deriving their just Powers from the Consent of the Governed"
Declaration of Independence -- July 4, 1776
To give our Bishops strength to cary out their mission:
"Most importantly of all, we call upon the Catholic faithful, and all people of faith, throughout our country to join us in prayer and penance for our leaders and for the complete protection of our First Freedom-religious liberty-which is not only protected in the laws and customs of our great nation, but rooted in the teachings of our great Tradition. Prayer is the ultimate source of our strength-for without God, we can do nothing; but with God, all things are possible."

To defend the sanctity of marriage:
17. Now, since the family and human society at large spring from marriage, these men will on no account allow matrimony to be the subject of the jurisdiction of the Church. Nay, they endeavor to deprive it of all holiness, and so bring it within the contracted sphere of those rights which, having been instituted by man, are ruled and administered by the civil jurisprudence of the community. Wherefore it necessarily follows that they attribute all power over marriage to civil rulers, and allow none whatever to the Church; and, when the Church exercises any such power, they think that she acts either by favor of the civil authority or to its injury. Now is the time, they say, for the heads of the State to vindicate their rights unflinchingly, and to do their best to settle all that relates to marriage according as to them seems good.
18. Hence are owing civil marriages, commonly so called; 'hence laws are framed which impose impediments to marriage; hence arise judicial sentences affecting the marriage contract, as to whether or not it have been rightly made. Lastly, all power of prescribing and passing judgment in this class of cases is, as we see, of set purpose denied to the Catholic Church, so that no regard is paid either to her divine power or to her prudent laws. Yet, under these, for so many centuries, have the nations lived on whom the light of civilization shone bright with the wisdom of Christ Jesus.
