Jesus became the Christ at His baptism

The Watchtower book, Holy Spirit - The force behind the coming new order, printed in 1975 says that Jesus became the Christ at His baptism. This is not true. Jesus was born the Christ as it says in Luke 2:11, "for today in the city of David there has been born for you a Savior, who is Christ the Lord," (Luke 2:11, NASB). It is clear that the Watchtower Organization was wrong about this.

"When did this Jesus become actually 'Christ the Lord'? Not on the eighth day of his birth, when he was circumcised. He was not anointed on that day. It was when he was thirty years old." ("Holy Spirit - The force behind the coming new order," 1975, p. 90.)	"Jesus was anointed with holy spirit after his baptism in water and he thus became Christ or Anointed One, so too with his disciples." ("Holy Spirit - The force behind the coming new order," 1975, p. 113.)
