Earnest; verse 15 was intended to mean that Christ was firstborn in the sense that he was the first of many (i.e. priority in time), then quite clearly all other things were created by him, as he did not create himself
Are you implying then, that the NAS, KJV etc..contradicts itself by not having [other] in v16?
I dont want to debate trinity values, however the NWT is quite clear in John 1:3 "and apart from him not one thing came into existence. What has come into existence."
What do you mean, Christ was the first of many, many what? Firstborn does not mean first created exculsively.
Would not Paul choose to use one of the two Greek words for "other": allos which means another of the same kind; and heteros which means another of a different kind? I believe Paul could have shown that Jesus was another "created being" if that where the case.
