to everyone who believes they are better than I am because they believe, damn you. we are all equal.

Marco, Kraków, Poland

For 'Faith' to exist, it is incumbent on Un-substantiation.

Funny how the 'aye' camp now want to turn the tables and 'demand proof'.

Dave, Tullamore, Eire

i hate to say it i was born a roman catholic and it took me 25 years to see through the cant and lies of religon there is no god only sad people too scared to enjoy life.

david west, sheffield, uk

Be careful guys. Tough days are coming. If the tories win the election they might change the rules for ASA, so that they might become asymmetric, something like: "everything doubt about religion constitutes an offense". This is happening elsewhere in the world (sadly!).

Mary, Aberdeen, UK

It's a shame Stephen Green didn't notice that the ASA's codes cut both ways. I will be looking forward to churches not being able to make unsubstantiated claims like "jesus loves you" - without adding a honest caveat like "theoretically".

Leila, Herts,

Ha Ha! “It is given as a statement of fact and that means it must be capable of substantiation if it is not to break the rules." It isn't given as a statement of fact. That is why it says "probably" and not "definitely." Man these religious folk are complete idiots.

Nathan, Rochester, United States

If I said I believed in a flying spaghetti monster, the burden of proving his existence would fall on me rather than everyone else. Despite what Stephen Green says, there isn't a shred of solid evidence for gods existence. I hope christian propaganda billboards are forced to use the word 'allegedly' in future.

Fraser Smith, Motherwell, Scotland

Souldn't Christian Voice just turn the other cheek?

JOhn, Newcastle-upon-Tyne, UK

typical backlash. Though it's not as if they put "there is no god" on the buses.

Edward, High Wycombe,

hahahahahahahahahaha

Idiots !

now which side am i talking about........ :-)

matt, bracknell, uk

I can't see why adverts that promise hell and damnation (like that one which inspired Arianne Sharine to respond with this campaign) should be allowed while the mere and humble hypothesis issued by the atheists shouldn't. It' the first one to be deceptive and inaccurate given that there's no proof.

John, Cambridge, UK

It's a stupid campaign and the so-called Christian Voice are as stupid by responding to it, but that was always the intention.
The whole business goes to show that the world won't actually be a better place once religion is outlawed. Atheism can produce morons just a easily as churches can.

Pedro Conejo, Puerto Cabras, Spain

Logically speaking, it hasn't broken the truthfulness section since the advert does not actively say "there is no god". It merely offers an opinion and allows people to think about the idea and make their own decisions.

Ben, Portsmouth, UK

If I were God and these arrogant little heretics demanded that I prove my existence merely in order to uphold their petty complaint, I think I'd know WHERE to send the thunderbolt!

Ian Kemmish, Biggleswade, UK

By the same token then, every church that mentions god when advertising its services should also say probably as there is no proof that god does exist. This green must be a major league putz to be so trivial.

Chris, Derby,

On the "Christian Voice" website, Stephen Green claims that "Parliament has legislated against every single one of the Ten Commandments" so I'd guess that both substantiation and even transubstantiation are - as it were - out to lunch.

Ian, Berwick, UK

I think that the word probably is a "get out of jail free", card? and their is NO evidence that their is a God. If Stephen Green, thinks that nature is evidence, then he should look closer at how disgusting nature can be. Let no God be so evil as nature can be.

John Santilli, Rome, Italy

The sooner religion is totally outlawed, the better place the world will be.

Paul , Milton Keynes, UK

Oh, marvellous. Advertisers are free to say "probably the greatest <product> in the world" so regularly that it's become a cliché... but as soon as someone suggests that someone else's baseless claims are "probably" untrue, there's a fuss? Un-believable.

brian t, Dublin, Ireland

typically pathetic. how is every church readerboard / sign across the nation proclaiming gods existence (including all of those church reader boards proclaiming "he is risen" after easter) any different?

jeez, the things i've read on those boards.. "you will go to hell if you don't believe" etc etc

Adam, Seattle WA, USA

Stephen Green of the Christian Voice Lobby is afraid of debate about God as are many believers. Lack of confidence in one’s own beliefs is sad to see, especially in friends, senior politicians, and clerics. Idea for follow-on: "There's probably no God, so stop worrying, and lead a GOOD life."

Paul Muller, Mae Sot, Thailand

I think Mr Green is confusing opinion and belief with evidence. Whilst he is correct in saying there is no evidence that God doesn't exist there is similarly no evidence that he does. EWveryone is entitled to their own opinion- it doesn't make it correct on either side.

Peter, London, UK

I believe in God but dont understand why anyone would object to this poster. Posters outside churches proclaim Gods existence so does that come under the same advertising rules?. The majority of people will not be swayed by advertising but will make up their own minds based on their own experience.

AL, Taunton,

It has always been said that in the face of lack of proof of the existence of a god or gods, faith must suffice. It appears to me that Mr. Green wants one law for the believers and another for the non-believers.

JTurner, Spalding,

is this article a joke? Mr Green! No more is there proof for God than against. and if this ad is illegal then so are all the Christian ads!

Marco, Kraków, Poland

This is just a ridiculous advertising stunt. Atheism denies the existence of the self - since you are just a collection of chemicals, there is no 'you' and even 'enjoyment' does not really exist. In fact, atheism is very, very sad.

Simon, Birmingham, Britain

There is no physical evidence for the existence of god either, so should we be prosecuting the churches of Christians, Muslims, Hindus et al?

Stuart Dickson, Palma Mallorca, Spain

Len - are you seriously suggesting that what the ASA says makes the slightest difference to the truth? What matters is objective logic and this does indeed deny the tiresome & primitive superstition that God does not exist.

Simon, Birmingham , Britain

The use of the word 'probably' is not a statement of fact, in the same way as the use of the word 'can' in breakfast cereal adverts (as in it 'can' lower your cholestrol) is not a statement of fact. Christian voice is out of its depth on this and is trying to win on subjectivity. Let science decide.

Andy, Liverpool, UK

If this claim is capable of objective substantiation I'll be most impressed - or for that matter the counter-claim!

Paul Freeman, London, England

It says probably. That is legal.
I don't see Christians saying probably when they advertise.
Freedom of speech in 2009 when we should have outgrown primitive superstitions anyhow.

Len, Oban, UK
