There is on earth among all dangers, no more dangerous thing than a richly endowed and adroid reason, especially if she enters into spiritual matters which concern the soul and God. For it is more possible to teach an ass to read than to blind such a reason and lead it right; for reason must be deluded, blinded, and destroyed.
Martin LutherAlso when it is a case of only upholding some spiritual tenet, such as infant baptism, original sin, and unnecessary separation, then . . . we conclude that . . . the stubborn sectaries must be put to death.
Martin LutherO, when it comes to faith, what a living, creative, active, powerful thing it is. It cannot do other than good at all times. It never waits to ask whether there is some good work to do.
Martin Luther
