As somebody who did a philosophy degree, I fully appreciate just how indebted science is to philosophy and Ockham's razor (and am well aware of it's origins). I'm not sure if your post was directed towards me or not, but if anything my post was in defense of religion. As I said, science can show (using Ockham's razor, one of the scientific process's most basic tenets) that God does not need to exist, but it can't show that God doesn't exist.
The origin of Ockham's razor does not make it any more or less valid in its use.
The post wasn't directed at you. It was an additional comment not a criticism.
Anyway - I am a Christian. I think that implies not only belief in Christ but commitment to him. Reason can lead you to the edge of Christianity, at least to the point at which its claims seem plausible. To be a Christian you must have taken further steps into faith. The word 'faith' we use relates to the Greek
pistis. That word implies not only belief but faithfulness in relationship. It indicates a commitment beyond mere belief.
I was raised in a Baptist Church, where you were encouraged not to think of yourself as Christian until you had made a commitment (unlike several other Churches they only baptise adults). My reasons for coming to believe were perhaps initially arrived at due to finding Christian claims of prophecy fulfilment convincing. So that belief led to an initial Christian commitment and to Baptism. This was cemented rather strongly by experiences I attribute to the presence and action of God. To pick a couple, I'll include seemingly miraculous healing to myself and close relatives and what seemed to me like literally feeling God's presence. There are plenty more. Later I underwent something of a crisis of faith, where I seriously doubted Christianity's historical claims. Reluctantly I started looking into the earliest details of Christianity, expecting to find a gaping hole. It was after in looking into them in detail that I realised that reason alone can take you to the point where you can be reasonably confident that you have the writings of those that knew Jesus and believed in his resurrection. The question that remains is simply
do you believe their claims?. That's where faith steps in for me.
I used to think of myself as a Conservative (theologically not politically) Evangelical but I can no longer claim that. I would still think of myself of evangelical, in that I hold Scripture in high regard. Having said that, my view of Scripture has changed considerably. I now recognise that the Bible is a thoroughly
human book. It is also something more - similar to how Christians believe that Jesus was thoroughly God and thoroughly man. Even so, I must recognise that it was written, edited and compiled by the early Church. To have faith in the bible one
must have faith that God was active in the early Church. That was a big pill to swallow for me. I would no longer regard myself as Baptist as I disagree with them theologically on a few points. The church I currently go to is officially mutidenominational (Anglican, Baptist and House Church) and I feel I can be myself there.
Someone has mentioned faith in the Bible as being a defining feature of Christians. The earliest Christians did not have our Bible in complete form. Most of the early creeds were in responses to particular points of interest. The Nicene Creed is, however, regarded by most of today's Christians as being a defining mark of Christianity. That reads:
I believe in one God the Father almighty, Maker of heaven and earth, and of all things visible and invisible.
And in one Lord Jesus Christ, the Son of God, the only-begotten, begotten of the Father before all ages;
Light of Light, true God of true God, begotten, not made, of one essence with the Father, by whom all things were made.
Who for us men and for our salvation came down from heaven, and was incarnate of the Holy Spirit and the Virgin Mary, and became man; and was crucified also for us under Pontius Pilate, and suffered and was buried; and the third day He rose again according to the Scriptures; and ascended into heaven and sitteth at the right hand of the Father.
And He shall come again with glory to judge the living and the dead; of His kingdom there shall be no end.
And in the Holy Spirit, the Lord, the Giver of life, Who proceedeth from the Father, Who with the Father and the Son together is worshipped and glorified, Who spake by the prophets.
In one Holy Catholic and Apostolic Church;
I confess one baptism for the forgiveness of sins;
I look for the resurrection of the dead
and the life of the age to come. Amen.
I accept that, but I also accept that I can only attribute my acceptance of minor parts of it to reason. The rest comes by faith. Christianity is something of a full package thing. So that's a belief statement that sums up what most Christians would regard as Christian belief. I've used the Orthodox version, as it's closer to the original wording than the version used in Western Churches (some of the suff about the Holy Spirit in Latin doesn't translate very well back into Greek, leading to a big argument that's been going on about 1000 years...)
Recognising that the Nicene Creed is a slightly modified version of something agreed in 325AD, I would want to simplify the definition of Christian. The earliest Christians had only fragments of the New Testament and no Nicene Creed. With that in mind I would put forward my definition: A Christian is one who can sincerely say "Lord Jesus Christ, have mercy on me: a sinner."
Anyway - sorry if that's straying too far off the Dawkins topic. As an aside I am a professional geologist, believe in evolution by natural selection and a 14 BN year old universe etc etc. I see no conflict between that and my faith or othodox (deliberate small 'o') Christian faith in general (just like to clarify that sort of thing early on when this comes up...).
