Galatians 3:26-29
"For ye are all the children of God by faith in Christ Jesus. For as many of you as have been baptised into Christ have put on Christ. There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus." (KJV)
" Y OU are all, in fact, sons of God through YOUR faith in Christ Jesus. For all of YOU who were baptized into Christ have put on Christ. There is neither Jew nor Greek, there is neither slave nor freeman, there is neither male nor female; for YOU are all one [person] in union with Christ Jesus." (NWT)
"YOU are all, in fact, sons of God through YOUR faith in Christ Jesus. For all of YOU who were baptised into Christ have put on Christ. There is neither Jew nor Greek, there is neither slave nor freeman (* - See footnote), there is neither male nor female; for YOU are all one [person] in union with Christ Jesus." (New NWT)
(* Footnote - Note this obviously does not include the faithful and discreeet slave class, else this verse would not agree with other passages of Scripture.)
The committee have decided to leave this verse just as it was because it will help add to the confusion of the rank and file to leave certain things in. Then they will just realize they cannot understand the Bible without the help of the "faithful and discreet slave class".
