It was not until the gift of the restored Greek Bible text through the researches of that rebel Catholic, Desiderius Erasmus Roterodamus, that brought Christian reason back into practice; and with it, the propagation of The Faith by preaching the Gospel and practical application of it through reliance on the authority of the Holy Scriptures alone.
From that rebirth of New Testament principles came also the congregational form of church polity, and eventually the republican democracy vested in our representatives by the Constitution. The systems of statist religion, whether Islamic or other, cannot coexist with the model supplied by America's Founding Fathers, but must wipe it out.
And that is why we must reject further diluting what remains of our already-tainted ideals by refusing immigration or nurturing of Islamists who will become influential, policy-making, freedom-destroying voters.
