Matthew Poole and continuators on John 5:18

18 Therefore the Jews sought the more to kill him, because he not onely had broken the Sabbath , but said also, That God was his Father, making himself equal with God .

This yet enraged the Iews more: They had before against him a Charge of breaking the Sabbath, or at least, teaching another to break it, (in their Opinion)

but now he had (as they judged) spoken Blasphemy, calling God Father; not in the sense the Iews so called him, and all good Christians are Licensed to call him; but [non-Latin text not transcribed], his proper Father, or his own Father; by which (as they truly said) he made himself equal with God. Nor did he by that alone, make himself equal with God, but he ascribed also to himself a co-operation with God, in works proper to God alone: Nor did he think this any Robbery, Phil. 2.6. This was their Charge; we shall now hear how our Saviour defendeth himself against it.
