“In a long and eventful life", the Doctor said eventually, "I have experienced nothing that I could not account for by the laws of physics, chemistry or biology. If a God or Gods exist, and I cannot rule out the possibility, then I can only presume that He, She or They take no active part in the lives of the many and various creatures that populate this extensive and wonderful universe of theirs". He picked a crumb of cheese from his plate and swallowed it. "In addition, I have seen countless races worship, countless Gods with attributes which are mutually incompatible, and each race believes itself to be following the one true faith. While I respect their beliefs, I would consider it arrogance for any race to try and impose their beliefs on me, and if I had a belief of my own then it would be equally arrogant of me to impose it on them. In short, sir, I am currently an agnostic, and by the time my life draws to its close, and I have travelled from one side of the universe to the other and seen every sight there is to see, I firmly expect to be an atheist".”
“People are invariably surprised to hear me say I am both an atheist and an agnostic, as if this somehow weakens my certainty. I usually reply with a question like, 'Well, are you a Republican or an American?' The two words serve different concepts and are not mutually exclusive. Agnosticism addresses knowledge; atheism addresses belief. The agnostic says, 'I don't have a knowledge that God exists.' The atheist says, 'I don't have a belief that God exists.' You can say both things at the same time. Some agnostics are atheistic and some are theistic.”
“The most formidable chains are forged from beliefs. Ah, beliefs! Beliefs tear out the eyes and leave us blind and groping in the dark. If I believe in one proposition, I have become locked behind the door of that belief, and all other doors to learning and freedom, although standing open and waiting for me to enter, are now closed to me. If I believe in one God, one religion, yes, if I believe in God at all, if I have closed my mind to magic, to spirit, to salvation, to the unknown dimension that exist in the firmament, I have plunged my mind into slavery. Test all beliefs. Distrust all beliefs.”
“My belief in God is personal, I do not need to browbeat anyone into agreeing with me, because I believe what I believe and I try to live by it. My belief in God is about trying to be the best person I can be in this life ...”
“I have come to the conclusion that the most important element in human life is faith.If God were to take away all His blessings, health, physical fitnes, wealth, intelligence, and leave me but one gift, I would ask for faith –- for with faith in Him, in His goodness, mercy, love for me, and belief in everlasting life, I believe I could suffer the loss of my other gifts and still be happy....”
“The desire for my "rights" in order to preserve my individuality (rather than allowing God the full right to take over my life and to perfect my personality) has to be stripped away. I have to learn to persevere in the race He has set before me, drawing strength only from Him, and not relying at all on what I may consider any natural abilities I may have. I have to let God take from me even that strength which I thought I had in order that He may more fully reveal His own strength: in order that He may continue in me the work of conforming me to the image of His Son.”
