“Too many religious people make faith their aim. They think 'the greatest of these' is faith, and faith defined as all but infallible doctrine. These are the dogmatic, divisive Christians, more concerned with freezing the doctrine than warming the heart. If faith can be exclusive, love can only be inclusive.”

“It is taboo in our society to criticize a persons religious faith... these taboos are offensive, deeply unreasonable, but worse than that, they are getting people killed. This is really my concern. My concern is that our religions, the diversity of our religious doctrines, is going to get us killed. I'm worried that our religious discourse- our religious beliefs are ultimately incompatible with civilization.”

“Does it never strike you that doubt can be a madness, as well as faith? That asking questions may be a disease, as well as proclaiming doctrines? You talk of religious mania! Is there no such thing as irreligious mania?”

“The doctrine that future happiness depends upon belief is monstrous. It is the infamy of infamies. The notion that faith in Christ is to be rewarded by an eternity of bliss, while a dependence upon reason, observation and experience merits everlasting pain, is too absurd for refutation, and can be relieved only by that unhappy mixture of insanity and ignorance, called 'faith.”

“Fatigue can make it hard to have faith. Too much busyness can make it hard to have faith. Too much of too little solitude can impact faith. For that matter, so can a bout of hunger or overwork, anything carried to an extreme. Faith thrives on routine. Look at any monastery and you will see that. Faith keeps on keeping on.”

“The aim of all Christian education, moreover, is to train the believer in an adult faith that can make him a "new creation", capable of bearing witness in his surroundings to the Christian hope that inspires him.”
