"Pick and choose" is a famous and not entirely accurate or complimentary broad-brush phrase which I think gives short shrift to how belief and faith are formed -- at least for some people, and perhaps many more than one might suppose. However, it is one of the phrases from the atheist arsenal which I think indicates exactly the atheist lack of insight that I take exception to.
Am I supposed to understand that atheists "think" and "reason" while believers only "pick and choose"? Or that only atheists have brains and others don't? Shorthand pejoratives don't really further understanding in a discussion such as this.
Let's take Christianity as a way of studying this point.
According to the
Bible, Jesus is supposed to have said that he wasn't on Earth to usurp the old law, but to develop it.
So one could start by pointing out that
Old Testament law is still supposed to be relevant for Christians today (unless, of course, 'times change' and certain things have become irrelevant in our modern world – which leaves a different problem, of whether the
Bible could thus be viewed as divinely inspired, since it would then seem that God did not plan or have control over what would happen in the future, and the
Bible is not, therefore, a totally trustworthy or relevant book for today). But I digress.
Nobody – not even the most fundamentalist Christian – takes the entire
Bible as (forgive the phraseology) as gospel. Nobody abides by all the rules and regulations. People pick the bits that they consider convenient to them. So they might remember the stuff about homosexuality in
Leviticus – but conveniently ignore the other stuff from the same book, about owning slaves, offering doves to priests after your period etc.
Let's go further – set aside the
Old Testament and let's just examine the
New Testament. Take Christ's teaching on money. How many Christians heed the advice that: "it's easier for a camel to pass through the eye of a needle than for a rich man to enter the kingdom of God"? How many Christians do as Jesus instructed the rich man who wanted to be a disciple – sell all their possessions, give the money to the poor and return to follow Christ? Tithing isn't what Jesus mentioned – but giving away all possessions. Once you say: 'well, that's not realistic in today's world', you say that you know better, to some degree or other, than the son of god. In making such a decision, you show, equally, a lack of faith in god's ability to look after you on Earth. It's a pragmatic decision, certainly, but it's not based on faith, and it is a choice to
not take on board something that is quite clear in the
Bible.
Let's take another little point – how many Christians actually believe that capital punishment is a good thing? In the US, I suspect that that's a particularly salient point given the numbers of Christians on the political right. Yet Jesus quite clearly told his followers to "turn the other cheek". So, some followers just dump that bit of teaching, because it's not convenient.
One might suggest, in terms of the US and its foreign policy, that quite a few Christians also dump "blessed are the peacemakers" – although perhaps that wouldn't be as good for the military-industrial complex? For a country whose leaders have, in recent years, proclaimed Christianity, they also seem to forget that "the meek shall inherit the Earth" and the "merciful shall obtain mercy".
Those are just a few points, but they illustrate that very, very few people who describe themselves as Christians really live out the teachings of the
Bible to the full, as they appear in that supposedly divine book. People pick what they find convenient and easy-to-do, and quietly forget the rest.
