Famous quotes containing the word glass:

    “More Safe, and much more modest ‘tis, to say
    God wou’d not leave Mankind without a way:
    And that the Scriptures, though not every where
    Free from Corruption, or intire, or clear,
    Are uncorrupt, sufficient, clear, intire,
    In all things which our needfull Faith require.
    If others in the same Glass better see
    ‘Tis for Themselves they look, but not for me:
    For MY Salvation must its Doom receive
    Not from what OTHERS, but what I believe.”
    —John Dryden (1631–1700)
