John 5:18 says
"Because of this, the Jews tried all the harder to kill Him. Not only was He breaking the Sabbath, but He was even calling God His own Father, making Himself equal with God."
Biblical Unitarians typically interpret this passage as the Jews being incorrect in claiming Jesus was making Himself equal with God, as a theme in John is people not understanding what Jesus is saying or who He is (this is made clearer at John 8).
Do Trinitarians agree that at this point in John's Gospel the Jews had adequate grounds to make the claim that Jesus was making Himself equal with God?
