As Ronald Reagan said in his farewell address to the nation, "I've spoken of the Shining City all my political life. …In my mind it was a tall, proud city built on rocks stronger than oceans, windswept, God-blessed, and teeming with people of all kinds living in harmony and peace; a city with free ports that hummed with commerce and creativity. And if there had to be city walls, the walls had doors and the doors were open to anyone with the will and the heart to get here. That's how I saw it, and see it still."
I guess Winthrop isn't the only one using the scriptural reference.
