At Isaiah 43:12, Jehovah said to His fleshly nation of Israel, "You are my witnesses." After Christ's death, the literal Jewish nation was cast off as God's chosen people, (Matt. 21:43) and Jehovah now allowed Gentiles to join those Jews who accepted Christ as the Messiah, to become part of the 'Israel of God'. (Galatians 6:16) At Acts 1:8, Jesus told members of the 'Israel of God' that they would witnesses of him, to the most distant parts of the earth! Following this, Acts 11:26 tells us that God Almighty chose the name for this 'new nation' who would be followers of His son Christ Jesus - Christians! However, in the early 20th Century, a man decided to change this God-given name, to one of his own choosing and interpretation. Reasoning on the Scriptures above, which name is more appropriate?
