If God was love (and real), there wouldn't be Evangelicals and Fundamentalists. Radicals wouldn't harm innocent people because their ideology isn't the same. Donald Trump would never have even been CONSIDERED, let alone elected President. Men like Roy Moore would not be allowed to proudly proclaim their love of "God." Paul Ryan would be deposed for his antagonism toward those who suffer. BUT... that's if God was love.

An invisible idea of humans with what is said to have great power but forgives rather easily!

Each and every person is unique in the idea of "god" that they claim to believe! They seem to believe in what they are told to believe without question!! Stupid followers!!

A primitive attempt to explain the universe.

Would your teacher friend be equally comfortable with the proposition that love is god?

The experience of caring for others and feeling cared for has profound influence over us. Love one another has been called the golden rule of Christianity. I once had a teacher in Catholic school say to me, if that is all you understand, then you understand. Of course a lot of people have different takes on what Christianity is and use to bible to suggest a lot of things that don't have logic or reason. Happiness though, while subjective, I think relates to most as something we wish to achieve. I've read that people who volunteer, engage in charitable acts, tend to report themselves happier and healthier than other who do not. That I believe counts as some social science research lending to the idea that love one another is the way to free yourself into a more pleasant state of being. Whether you call it god or simply the way it is.. what do they say, that god is the truth and the way? We don't have to agree on everything to agree on a kernal of truth. Scientists are looking for truth and a way of getting to it anyway, so there is a lot of common ground in this.

Our ignorance.

“No one infers a god from the simple, from the known, from what is understood, but from the complex, from the unknown, and incomprehensible. Our ignorance is God; what we know is science.” ? Robert G. Ingersoll

dog backwards.

A figment of imagination.

An idea!! Figment of believers of the 'invisible guy in the sky' imaginations! Dont get me wrong the human brain is crazy powerful and we may never know its capabilities

“God is a concept by which we measure our pain.”
—John Lennon

I'd say your friend was being disingenuous in her response. The "God is love" remark, while poetic in a cheap greeting card sort of way, has little to do with Catholic theology in any meaningful sense. They don't believe that God is an impersonal emotion; they believe in a personal, omnipotent God who created the world and everything in it, and who set forth rules for us to live by and will reward or punish us for all eternity based upon how well we follow his rules. They believe God to be a Trinity of persons (a required belief for Catholics), one of which was born of a perpetual virgin (also a required belief). To say simply "God is love" is ignoring pretty much the entirety of the religion.

Some people say that god is a belief in a supernatural being for which there is no evidence. Others, might say it a word that seems to satisfy or 'fill a gap' in the lives of many people. What does the word mean to you?

You can put the name of god (with a small letter) on anything you want - it might not mean the same thing to all people. We have stated meanings for god/goddess that we all understand - For me, the Christian God IS a Being (Old man with a beard in the sky that sits on a throne and judges everything). Some people never progress beyond this.
I would think that God is actually your own idea of what is right or wrong. Prayer is a sort of meditation for our hopes and wishes. No need for supra-human type miracle worker.
Love is an emotion, which is what we all want and sort of dry up without. But God or god - define your term...Christian God, Pele, Baal, etc.
God is just an idea...unseen, unheard, unfelt - just an idea to try to explain the unexplainable.

a load of shit

I don't know much about Catholicism. I once went to a Greek Orthodox wedding? But as far as god is concerned doesn't everyone have their own definition of god? I used to think god was your conscience.

God is the ideal human. It is a state of moral & ethical existence which is unattainable. God is depicted as all powerful, all knowing & all seeing. Saying that humans were built in gods image may mean that the collective human species, humanity, is the embodiment of god.

Scientifically, God is a state of mind which is only attainable in 2nd generation humans. 2nd Gen humans have an intellectual capacity which far exceeds the average level. They only engage in worthwhile pursuits & do not bother with trivial activities.

A single human can only ever become 75% of what is described to be a God. Apart from the mental development & ability to bring about social & cultural changes in history. Human beings can be killed or can die. God is believed to be immortal & humans are not.

“God” is a metaphor for the combined forces and influences that affect you, over which you have no control.

This planet with its trees and mountains and oceans and valleys.... the stars in the sky.... the seasons.... a child flying a kite on a warm breezy day...... So you get it? GOD IS YOUR SENSES....

What Color Is God?
