I have studied these things — you have not. - Isaac Newton

In the first ages of the Christian religion the Christians of every city were governed by a Council of Presbyters, and the President of the Council was the Bishop of the city. The Bishop and Presbyters of one city meddled not with the affairs of another city, except by admonitory letters or messages. Nor did the Bishops of several cities meet together in Council before the time of the Emperor Commodus: for they could not meet together without the leave of the Roman governors of the Provinces. But in the days of that Emperor they began to meet in Provincial Councils, by the leave of the governors; first in Asia, in opposition to the Cataphrygian Heresy, and soon after in other places and upon other occasions. The Bishop of the chief city, or Metropolis of the Roman Province, was usually made President of the Council; and hence came the authority of Metropolitan Bishops above that of other Bishops within the same Province. Hence also it was that the Bishop of Rome in Cyprian's days called himself the Bishop of Bishops. As soon as the Empire became Christian, the Roman Emperors began to call general Councils out of all the Provinces of the Empire; and by prescribing to them what points they should consider, and influencing them by their interest and power, they set up what party they pleased. Hereby the Greek Empire, upon the division of the Roman Empire into the Greek and Latin Empires, became the King who, in matters of religion, did according to his will; and, in legislature, exalted and magnified himself above every God: and at length, by the seventh general Council, established the worship of the images and souls of dead men, here called Mahuzzims.

And so, supposing that light impinging on a refracting or reflecting ethereal superficies puts it into a vibrating motion, that physical superficies being by the perpetual applause of rays always kept in a vibrating motion, and the ether therein continually expanded and compressed by turns, if a ray of light impinge on it when it is much compressed, I suppose it is then too dense and stiff to let the ray through, and so reflects it; but the rays that impinge on it at other times, when it is either expanded by the interval between two vibrations or not too much compressed and condensed, go through and are refracted.
