The article is highlighting the fact that even though it might seem that people are becoming less religious...ie. leaving major religious groups...they are in fact not giving up their Faith. Their Faith is taking different forms.
I know that's what the article claims, but doesn't provide any credible evidence in support of that claim, unlike the Pew research I linked to, which doesn't support their view that people aren't becoming less religious, merely describing their faith as spiritual.
Did you actually read the Pew research Sriram? Perhaps I can summarise, using the UK as an exemplar, although the UK situation is pretty similar to other European countries.
So the argument from your article goes as follows: Ask people if they are religious or non-religious and you get a decline in religiosity. Add in a third option of 'spiritual', and you uncover a large group of people who in a binary choice pick non-religious but now define as 'spiritual'. Effectively that in a three way choice the proportion of people indicating religious and/or spiritual is greater than those that indicate religious in a binary choice. Put another way that in a three way choice fewer people say they are neither spiritual nor religious than say they are non-religious in a binary choice.
The problem with that argument is it is not borne out by the evidence.
So in the Pew research, firstly there are very few people (just 6% in the UK) who say they are spiritual but not religious.
Secondly and much more significant - the proportion of people saying they are neither religious nor spiritual in the three option choice (55%) is pretty well identical (actually slightly larger) than the numbers who say they are non-religious in a binary choice. So it doesn't matter if you describe 'faith' as 'religious' or as 'religious and/or spiritual' you get to the same number, and you get the same number that say they aren't religious in a binary choice or aren't 'religious and/or spiritual' in the three-way choice.
So rather than revealing a subset of non-religious people who will say they are spiritual if given the option, all this does is reveal a subset of people who say religious in a binary choice who prefer the term spiritual if given the option.
And of course there is no evidence that if you add 'spiritual' as a faith option that you somehow no longer see a decline - you do, and to the same extent as just asking religious vs non-religious as the proportions of the population saying they are non-religious (in a binary choice) is the same as saying neither religious nor spiritual in a situation that includes 'spiritual' as an additional option. And that proportion of the population saying they are religious and/or spiritual (44%) is way lower that typical numbers saying they were religious perhaps 30 years ago (approx. 65%) - so allowing people to indicate they are spiritual is having no effect on the decline in faith revealed by research.
That's my point Sriram - that your claim (and your article's) that
'the fact that even though it might seem that people are becoming less religious...ie. leaving major religious groups...they are in fact not giving up their Faith. Their Faith is taking different forms' is complete wishful thinking and not borne out by the evidence.
