John 5:17
For this reason they tried all the more to kill him; for not only was he breaking the Sabbath, but he was even calling God his own Father, making himself equal with God. — the authorities rightly perceive Jesus' claim: by working on the Sabbath in imitation of the Father and by calling God his own Father (idiotes: possessive intimacy), Jesus asserts equality with God. This is the central charge that drives the narrative toward crucifixion.
