Famous quotes containing the words john m and/or john:
“but when lust
By unchaste looks, loose gestures, and foul talk,
But most by lewd and lavish act of sin,
Lets in defilement to the inward parts,
The soul grows clotted by contagion,
Imbodies, and imbrutes, till she quite loose
The divine property of her first being.”
—John Milton (1608–1674)
“Pervading nationalism imposes its dominion on man today in many different forms and with an aggressiveness that spares no one.... The challenge that is already with us is the temptation to accept as true freedom what in reality is only a new form of slavery.”
—Pope John Paul II (b. 1920)
