What does it profit if one says.
" God is." = (theism).
"Jesus is God." = (Incarnation.);
yet say, "Jesus failed; thus, God failed." = (Impotence = atheism).
and say, "Our view of the atonement is irrelevant" = (Our view that God failed to save = Impotence = our atheism is also irrelevant");
Of course one's view of the atonement is relevant, of course one's atheism via idolatry is relevant.
