Contradiction with John 8:12
While John 5:35 describes John the Baptist as "a burning and a shining light," John 8:12 quotes Jesus as saying, "I am the light of the world," which may imply a contradiction in the source of spiritual illumination.
John 8:12: Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
Contradiction with John 1:8
This verse states, "He was not that Light, but was sent to bear witness of that Light," indicating that John was not the Light himself, potentially contradicting the depiction of John the Baptist as a light in John 5:35.
John 1:8: He was not that Light, but [was sent] to bear witness of that Light.
Contradiction with Matthew 5:14
Here, Jesus tells his followers, "Ye are the light of the world," suggesting a broader attribution of being a light to many, not just John the Baptist as highlighted in John 5:35.
Matthew 5:14: Ye are the light of the world. A city that is set on an hill cannot be hid.
