At the time of our Declaration of Independence, King George III was not only the King of England but also the Supreme Governor of the Church of England, also known as, the Anglican Church. At one time, England was indeed a true Catholic nation, subservient to the Pope, but because King Henry VIII was adamant that he would divorce his present wife so as to marry another woman and thereby to have a male heir, he was excommunicated by the Catholic church, and subsequently King George III created the separated Church of England with himself as the head of that church.
As a colony of England, America recognized that any governmental authority in which the head of it, was both the religious as well as the political leader, had both the ultimate authority over secular as well as religious faith, which was in point of fact a clear and present danger to the unalienable rights that each of us has had gifted to us by our Creator. This meant, that as part of the formation of our Constitution, America, in its First Amendment, made it clear that the Federal Government would not be permitted to establish a national religion, because by so doing this would compel its citizens to worship in a certain, specific way, under Federal aegis and approval, whereas we are created with the unalienable right to worship God in any way that we find pleasing to ourselves and our conscience.
The worship of our Creator, or non-worship, for that matter, is in America an individual choice. That is why there is no religious test ingrained in our Constitution, because the Founders of this great nation believed that each individual was entitled to their own freedom of conscience, rather than being compelled to believe in only one particular sect or in one particular faith. This means, in effect, that America is a country founded upon true religious liberty, something almost completely unheard of in the annals of history, and seldom truly practiced or adhered to.
Under our Constitution, ingrained within American law, is our freedom to worship God as we so desire, compelled not by Federal government authority to worship only the favored religion of the State, nor are we precluded from worshiping as per our conscience and our proclivity by Federal laws. This is the way that it should be, as our God, does not compel anyone to bend their knees to Him, and never will.
Not only do we have true freedom of religious worship and conscience in America, but unlike certain countries, that favor one religion specifically and hold all others as blasphemy or similar, this Federal government cannot favor one religion over all others, instead it is a level playing field, allowing each individual to find God in his own way, on his own terms, without Federal interference.
There are few things as important as our relationship to God as we see Him, and no country should have the implicit right to compel its citizens to respect that only this particular way is the way, instead each of us should be permitted to find our way to He who is the One who has disposed upon us free will and free conscience, in the hope that one day, we will live our lives in a manner that reflects that He is true love, true liberty, and true freedom.
