Art,
Nobody is saying that is not what we are to believe. The Gospel means good news, which is Jesus crucified and risen for our justification.  Is simply affirming those truths enough? Can a person who denies the Virgin Birth or His Deity yet affirm the fact he died and rose again be saved? The modernist will affirm that they believe that but questioned at length they have a different view about his resurrection. There is one belief that he he really did not die but simply swooned and the coolness of the tomb revived him, yet they claim that is a resurrection. The JWs affirm it as do Mormons, are they saved? What happened to repentance?

Proverbs 29:2 "When the righteous are in authority, the people rejoice: but when the wicked beareth rule, the people mourn."
