A cleric who loses his faith abandons his calling; a philosopher who loses his redefines his subject.

I haven't lost my faith, but I've lost my religion. I still believe in something so deeply. ... I've never really gotten past that quote from Anne Frank in her diary, where she says that people are really good at heart. But I feel like the Catholic Church — no — the Catholic hierarchy has been disinviting people like me, and especially women like me, for so many years that I finally took the hint.

For dear me, why abandon a belief
Merely because it ceases to be true

You can't lose faith you never had to begin with.
Ah. So you never believed in the Bright at all?
Of course I believed. Even now I believe, in principle. But when I was sixteen, I saw the hypocrisy in all the things the priests had taught me. It's all very well to say the world values reason and compassion and justice, but if nothing in reality reflects those words, they're meaningless.

As after the zeal of research and the satisfaction of learning displayed in a memorable pageant, Cornelius Agrippa became convinced that the sciences of his period were vain, including his own, so was he disillusionised in matters of official religion. But he did not become a protestant. His position is comparable to that of Paracelsus, who wished Luther and the chaos of reformers well, believing doubtless that something would evolve therefrom, but he did not join the reformers.

And I would shrug and play the question off, unable to confess that I could no longer distinguish between faith and mere folly, between faith and simple endurance; that while I believed in the sincerity I heard in their voices, I remained a reluctant skeptic, doubtful of my own motives, wary of expedient conversion, having too many quarrels with God to accept a salvation too easily won.

Belief clings, but faith lets go.

It is a mysterious thing, the loss of faith-as mysterious as faith itself. Like faith, it is ultimately not rooted in logic; it is a change in the climate of the mind.

...Today the lack of faith is an expression of profound confusion and despair. Once skepticism and rationalism were progressive forces for the development of thought; now they have become rationalizations for relativism and uncertainty.

When faith is completely replaced by creed, worship by discipline, love by habit; when the crisis of today is ignored because of the splendor of the past; when faith becomes an heirloom rather than a living fountain; when religion speaks only in the name of authority rather than with the voice of compassion — its message becomes meaningless.

When I studied modern Catholic literature in Rome a few years ago, I became convinced how hopeless it is to think that there are any scientific results this church cannot digest... I could not honestly participate in such anti-clericalism. It is true that I am absolutely unmusical in matters religious and that I have neither the need nor the ability to erect any religious edifices within me — that is simply impossible for me, and I reject it. But after examining myself carefully I must say that I am neither anti-religious nor irreligious. In this regard too I consider myself a cripple, a stunted man whose fate it is to admit honestly that he must put up with this state of affairs (so as not to fall for some romantic swindle)... For you a theologian of liberal persuasion (whether Catholic or Protestant) is necessarily most abhorrent as the typical representative of a halfway position; for me he is in human terms infinitely more valuable and interesting... than the intellectual (and basically cheap) pharisaism of naturalism, which is intolerably fashionable and in which there is much less life than in the religious position (again, depending on the case, of course!)'''

They said that I should lose my ideals and begin to believe in the methods of practical politicians. Now, I have not lost my ideals in the least; my faith in fundamentals is exactly what it always was. What I have lost is my childlike faith in practical politics.

I departed from parental paths significantly and abruptly one Sunday morning when, sitting in the family pew of the Hyde Park United Church and idly twisting a loose button on the cushion beside me, I said to myself, "I do not believe in God." Some months previously... when our minister fell back on St. Anselm's ontological argument to prove the existence of God, he entirely failed to convince me. Quite the contrary, the argument struck me as an abuse of language. Though I duly submitted to the ritual of confirmation... Horton's unconvincing argument had sown doubt in my mind; and for that reason I can assign, on that morning, listening to his more emotional, hortatory rhetoric... the balance tipped, committing me to a secret, personal rejection of the Christian piety my parents held dear.

A lot of folk who have lost faith in God it's a very healthy thing because the God they lost faith in was probably an idol anyway. The challenge becomes are you still open enough and vulnerable enough in your soul, to be open to something bigger than you thats connected to a love and justice, to an honesty, decency, and integrity. Secular folk will have their language for it, Jewish brothers and sisters have their language, Islamic brothers and sisters will have their language, and some of us will still put Jesus at the center of it.
