“What we know about God is important, but what we do with what we know about God is even more important. Too often people think it is necessary that we all see God in the same way (which is impossible anyway), but what is really necessary is that we all follow God according to what God tells us. The fact that God has given us so many different faces and temperaments and emotions and histories shows us how God honors each unique journey and culture. God is not threatened by differences. It’s we who are.”

Context: I have given my reasons for thinking that we can probably explain evolution in terms of the capacity for variation of individual organisms, and the selection exercised on them by their environment....
The most obvious alternative to this view is to hold that evolution has throughout been guided by divine power. There are two objections to this hypothesis. Most lines of descent end in extinction, and commonly the end is reached by a number of different lines evolving in parallel. This does not suggest the work of an intelligent designer, still less of an all mighty one. But the moral objection is perhaps more serious. A very large number of originally free-living Crustacea, worms, and so on, have evolved into parasites. In doing so they have lost, to a greater or less extent, their legs, eyes, and brains, and have become in many cases the course of considerable and prolonged pain to other animals and to man. If we are going to take an ethical point of view at all (and we must do so when discussing theological questions), we are, I think, bound to place this loss of faculties coupled with increased infliction of suffering in the same class as moral breakdown in a human being, which can often be traced to genetical causes. To put the matter in a more concrete way, Blake expressed some doubt as to whether God had made the tiger. But the tiger is in many ways an admirable animal. We have now to ask whether God made the tapeworm. And it is questionable whether an affirmative answer fits in either with what we know about the process of evolution or what many of us believe about the moral perfection of God.

1950s, Rediscovering Lost Values (1954)
Context: And I think, my friends, that that is the thing that has happened in America. That we have unconsciously left God behind. Now, we haven't consciously done it; we have unconsciously done it. You see, the text, you remember the text said that Jesus' parents went a whole day's journey not knowing that he wasn't with them. They didn't consciously leave him behind. It was unconscious; went a whole day and didn't even know it. It wasn't a conscious process. You see, we didn't grow up and say, "Now, goodbye God, we're going to leave you now." The materialism in America has been an unconscious thing. Since the rise of the Industrial Revolution in England, and then the invention of all of our gadgets and contrivances and all of the things and modern conveniences—we unconsciously left God behind. We didn't mean to do it. We just became so involved in getting our big bank accounts that we unconsciously forgot about God—we didn't mean to do it. We became so involved in getting our nice luxurious cars, and they're very nice, but we became so involved in it that it became much more convenient to ride out to the beach on Sunday afternoon than to come to church that morning. (Yes) It was an unconscious thing—we didn't mean to do it. We became so involved and fascinated by the intricacies of television that we found it a little more convenient to stay at home than to come to church. It was an unconscious thing—we didn't mean to do it. We didn't just go up and say, "Now God, we’re gone." We had gone a whole day's journey and then we came to see that we had unconsciously ushered God out of the universe. A whole day's journey—didn't mean to do it. We just became so involved in things that we forgot about God. And that is the danger confronting us, my friends: that in a nation as ours where we stress mass production, and that's mighty important, where we have so many conveniences and luxuries and all of that, there is the danger that we will unconsciously forget about God. I'm not saying that these things aren't important; we need them, we need cars, we need money; all of that's important to live. But whenever they become substitutes for God, they become injurious. And may I say to you this morning, that none of these things can ever be real substitutes for God. Automobiles and subways, televisions and radios, dollars and cents can never be substitutes for God. For long before any of these came into existence, we needed God. And long after they will have passed away, we will still need God.
