Even in the Christian congregation there may be an environment or association that is spiritually not most helpful. Some who recently came out of the world and symbolized their dedication to God by water baptism may tend to bring into the congregation something that still clings to them—a measure of worldliness. Let us remember that it was to a Christian congregation that the apostle Paul wrote: “In my [previous] letter I wrote you to quit mixing in company with fornicators, . . . But now I am writing you to quit mixing in company with anyone called a brother that is a fornicator or a greedy person or an idolater or a reviler or a drunkard or an extortioner, not even eating with such a man.”—1 Cor. 5:9-11.
This is a damning extract indeed.
Firstly it cruelly & selfishly recommends keeping away from new recruits who may really need Christian love & guidance.
Secondly it proves that disfellowshiping is not scriptural as Paul does not talk about forcing the 'idolator, drunkard,fornicatie, greedy person ' etc out of the cong but rarther to stop socializing closely with such people, actually not even shunning them as JW 's practice (ignoring).
They were busy looking after “orphans and widows in their tribulation”
I've yet to find a JW as individuals or congs who follow the direction of James and the 1st century Christians here.
