The gospel, which Paul defines this way - "that Christ died for our sins in accordance with the Scriptures, that he was buried, that he was raised on the third day in accordance with the Scriptures, and that he appeared to Cephas, then to the twelve" - this is what we believe, it is that in which we stand, that which we hold to. This is what we preach, and it is what we believe - Christ, and Him crucified. When you say that Christ is the object of our faith, you mean Christ who died for our sins and rose again for our justification, so you and I are saying the same thing.
