1.the one Supreme Being, the creator and ruler of the universe.
4.( often lower case) a supreme being according to some particular conception:the god of mercy.
OK, so using your definition: the creator owns everything and has the authority to establish right and wrong by virture of his nature as creator. But if he establishes what is wrong and refuses to punish wrong, that makes him an enabler of wrong doing does it not? He would be a contradiction of himself. So it seems like your God mush punish sin to be consistent with himself.
Further, wouldn't your God of Supreme Mercy find a way to also save?
This was all done in the Substitutionary Atonement which is what Terry has a problem with, hence the purpose of this thread.
Seems like your God would do the same thing Yahweh did, no?
