There was a huge time gap between the three gospels and John's gospel.The Gospel of John certainly appears as though it does, and anytime someone brings it up, you merely disqualify it. You can disqualify it if you want, but don't make it sound like the concept of Jesus' divinity is invented by Christians out of thin air. It does have some scriptural basis, whether you believe those scriptures or not.
So, until the arrival of John's gospel, no one had any idea about his alleged divinity. Right?
I do not find any divinity in John's gospel. John only wanted you to believe that he was the messiah, ignoring the Son of God addition in John 20.
