A typical JW answer. Watchtower has become a self-righteous Organization on the footsteps of Scribes and Pharisees in Jesus days.
On a complete different aproach Jesus was associating with prostitutes, tax collectors, and generally all those that the Pharisees consider them to be Am-Harets as they call them, meaning the people of the dust. Jesus gave emphasys to those people instead of the self righteous religious leaders.
WT is acting like a modern day Pharisee and ignores the fact that Jesus came for our sins. No matter what, no one can be saved, that is why Jesus said that even a bad thought is a sin. That is why through His Grace we are saved, and not by our works.
WT has fallen into a serious intepretation mistake. In the Greek Scriptures we find a different meaning from the WT's explanation. Apostle Paul stated clear: Μ? συναναμοιγν?εστε...the literal translation of this is: not mixing, and it is refering for the Holy Communion, when all Christians are becoming One, are united, through Jesus Blood and Flesh. This was the only time when a serious sinner was not allowed to partake the Holy Communion, and this was how the Early Apostolic Church understood the matter.
The Chruch is a place of spiritual healing, a hospital of the Soul, and not a place of pannishment like WT does.
