On the Prodigious Zeal of False Teachers -William S. Plumer-

“The amount of zeal displayed by false teachers is sometimes prodigious. They compass sea and land to make one proselyte. They often put to shame the lukewarmness of some who hold the truth. Their devoutness sometimes seems astonishing. In them Satan seems transformed into an angel of light. I have never seen more seeming warmth in religious worship than among some who deny the divinity of our Lord Jesus Christ and of the Holy Spirit. They are both sanctimonious and fanatical. They have fire, but it is wild fire. Let us follow no teacher merely because he is moral, zealous and apparently devout.”

On Tolerance, and Despair, and Nothingness -Dorothy L. Sayers-

“In the world it is called Tolerance, but in hell it is called Despair…the sin that believes in nothing, cares for nothing, seeks to know nothing, interferes with nothing, enjoys nothing, finds purpose in nothing, lives for nothing and remains alive because there is nothing for which it will die.”

Dorothy L. Sayers
