A religion is a system of symbols which acts to establish powerful, pervasive, and long-lasting moods in men by formulating conceptions of a general order of existence and clothing those conceptions with such an aura of factuality that the moods and motivations seem uniquely realistic.

Religion is a kind of life or experience.

Religion is to do something for God, to worship God, yet without [God]. Now I would add something more to this definition of religion. When we say something is religion, we also mean that you have more than one way to live in your human living. In one of the ways for living, you don't apply the spiritual teachings to your life. You live a life without God. You just live it by yourself.... As long as you make a spiritual thing only a section of your daily living and not your whole daily living, that is a performance. That is religion.

We define religion as the assumption that life has meaning. Religion, or lack of it, is shown not in some intellectual or verbal formulations but in one's total orientation to life. Religion is whatever the individual takes to be his ultimate concern. One's religious attitude is to be found at that point where he has a conviction that there are values in human existence worth living and dying for.

Religion as a word points to that area of human experience where in one way or another man comes upon mystery as a summons to pilgrimage; where he senses meanings no less overwhelming because they can be only hinted at in myth and ritual; where he glimpses a destination that he can never know fully until he reaches it.

Religion is the emulation of the adult by the child. Religion is the encystment of past beliefs: mythology, which is guesswork, the hidden assumptions of trust in the universe, those pronouncements which men have made in search of personal power, all of it mingled with shreds of enlightenment. And always the ultimate unspoken commandment is ‘Thou shalt not question!

Religion is the vision of something which stands beyond, behind and within the passing flux of immediate things; something which is real, and yet waiting to be realized; something which is a remote possibility, and yet the greatest of present facts; something that gives meaning to all that passes, and yet eludes apprehension; something whose possession is the final good, and yet is beyond all reach; something which is the ultimate ideal, and the hopeless quest.

Roughly, religion is a community's costly and hard-to-fake commitment to a counterfactual and counterintuitive world of supernatural agents who master people's existential anxieties, such as death and deception.

Religion in some form is a universal function of man in society, the organ for dealing with the problems of destiny, the destiny of individual men and women, of societies and nations, and of the human species as a whole. Religions always have some intellectual or ideological framework, whether myth or theological doctrine; some morality or code of behaviour, whether barbaric or ethically rationalized; and some mode of ritualized or symbolic expression, in the form of ceremonial or celebration, collective devotion or thanksgiving, or religious art...

Religion is a system of wishful illusions together with a disavowal of reality, such as we find nowhere else but in a state of blissful hallucinatory confusion. Religion's eleventh commandment is "Thou shalt not question."

Religion is being and becoming. Religion is the manifestation of the Divinity already in man.

religion is created by humans rather than by gods, and it is defined by its social function rather than by the existence of deities. Religion is anything that confers superhuman legitimacy on human social structures. It legitimises human norms and values by arguing that they reflect superhuman laws.

I need not stand here to repeat any definition of what religion is. I think you will all say that it is aspiration, the pursuit of the divine in the human; the sacrifice of everything to duty for the sake of God and of humanity and of our own individual dignity.

A religion is a kind of group dream—the subjective poetry in which, supporting one another’s faith or need to believe, we strive desperately to believe.
