I've never gotten a "true" definition of Christian from anyone. Now as to comparing the so called Christians of the Bible with those who call themselves Christian today, they were healers, martyrs, teachers, socialists, non political, cultists. Todays so called Christians are self righteous hypocrites....IMHO
There is a very common and cross cultural concept of what being a Christian means. Namely on the idea that Christ, or Joshua, was a semi-divine, or wholly divine, being sent to Earth by God as his only Son in order to sacrifice himself for humanities sins. Throughout the canonical Gospels as well as non-Canonical texts this idea remains. That Christ was sent by God to forgive humanity of it's Sins and that redemption was through the acceptance of this concept. Only a traditional school of gnosticism, rising later than the time period of Christ, argues against those specific ideals. However, throughout the cultural development of Christianity in the Middle East, North Africa, Europe and later the Americas the cultural norm has remained and the philological concept of a Christian has remained that a Christian is one who has accepted the divinity and sacrifice of Jesus Christ.
It is the most defining concept of the religion.
Thus later concepts attempting to paint themselves as "Christian" in some form, such as Christian Wiccans, while absolutely denying the long term traditions of not only the religious practices but the actual terminology itself are essentially.............. ********,
Imagine if I took the verifiable fact that my great, great grandmother was Jewish. She was. Up until whatever point in her life that she married a Christian ancestor of mine and adopted his tradition she was a Jew. To date I do not practice any Judaic traditions. I find most of them utterly useless and one of them utterly offensive. However, if I decided that my ancestor was really cool and adopted her definition of herself, prior to marriage, and told people I was Jewish while never observing Jewish traditions what would most people call me?
They would call me a dick.
Get that OP.
Understand it now?
But now to your description of Christians and your absolutely and utterly bigoted concept that today's Christians are so self righteous. That is an unsubstantiated view in itself. It's your opinion. And here is my opinion as a self declared atheist still living among a very faithful Southern Baptist family. The religious believers are the most caring and charitable people I've known.
So your honest opinion....in my honest opinion....is utter crap.
