First of all, Christianity isn't a cult. Here is the definition of a cult from the Oxford Dictionaries online:
1 - A system of religious veneration and devotion directed towards a particular figure or object, eg the cult of St Olaf
- A relatively small group of people having religious beliefs or practices regarded by others as strange or as imposing excessive control over members
- A misplaced or excessive admiration for a particular thing
2 - A person or thing that is popular or fashionable among a particular group or section of society.
Christianity is a faith or a religion. It arrived in the British Isles almost 2000 years ago. Pagan practices were the norm in pre-Christian Britain (and of course continue on to the present day). The early Christians - who were either Roman or Celtic in tradition and practice - are responsible for laying the foundations of the Christian values to which your post refers. I think you are being deliberately obtuse in what you say but if you want to discover which values embedded in our culture were established by the Christian church then you won't have to look very far because they are numerous and pretty fundamental in some cases. One has recently been the subject of new legislation: marriage. Marriage is a set of values, marked by a tradition (the wedding ceremony), which was established in this country by the Christian church. There were commitment ceremonies which pre-dated the Christian marriage but they were different from the marriage values which have been applied in the British Isles for centuries.
On your point about other religions sharing the values of Christianity: only two could be said to share some of the values. The primary one is Judaism, which predates Christianity. The other is Islam, which is a younger religion than Christianity. However, while they do share values, they do not share all values and in some areas they are fundamentally different.
there are sects within the cult of christianity which don't share the same values.
what are these values anyway? I suspect they transecend the teachiungs of religious cults.
