TheWonderofYou: Is the NWT really the only bible that gives in Gal. 6,16 the impression that christians replace Israel and are now the new Israel of God ?
That is really easy to check, Wonder.
The Bible Hub lists many different translations on their website - an easy google search

You will note that the NWT is not included in this lengthy list of bible translations/versions
Either interpretation of the verse can be found depending upon which bible you chose to read
