I think it is commendable that you want to do society good...but
your thinking is not just unrealistic, its pure naivity.
First of all, what are you talking about 'primitive
christianity' ? A small little church that is not a 'megachurch'.
The very first church at 1AD was like 200,000 strong. It taught
tithing, there was heirachy, leadership and structure similar to a
modern day church.
Without these basic functions of leadership and structure, no
organisation can function. Think of it like if your family has no
role who is the father, mother, son and daughter...the father will
cry at home and sell the daughter away to work, while the mother
plays computer games.
If you are against scripture and think that the church should
not be based on scripture alone, then why call it a church? Then
its just a club.
Then who is your God in this church? If you don't believe the
bible, then on what basis do you believe God, Jesus or the Holy
Spirit?
You're self contradiciting.
Then what's the purpose of its existence? To have fun? There're
so many other places more fun than your 'church'.
I seriously think.....you might need some psychological
help.
