Remove justice, and what are kingdoms but gangs of criminals on a large scale?... A gang is a group of men... in which the plunder is divided according to an agreed convention.

Thus the good christian should beware of mathematicians and all those who make false prophecies, however much they may in fact speak the truth; lest, being in league with the devil, they may deceive errant souls into making common cause.
In no passage of the holy canonical books there can be found either divine precept or permission to take away our own life, whether for the sake of entering on the enjoyment of immortality, or of shunning, or ridding ourselves of anything whatever. Nay, the law, rightly interpreted, even prohibits suicide, where it says, 'Thou shalt not kill.' This is proved especially by the omission of the words "thy neighbor," which are inserted when false witness is forbidden.
