Alluded to, its proclaimed paul said I declared. And not only that, he says that is of first importance! Look at the niv rendering of vs 3,4 For what I received I passed on to you as of first importance[a]: that Christ died for our sins according to the Scriptures, 4that he was buried, that he was raised on the third day according to the Scriptures,

And yes in this verse, it is the major emphasis, now grant it the emphsasis begins to merge into the subject of the resurrection, I see that. But in the mean time , the verses preceeding set forth the true gospel that paul received from heaven and that which he was accustmed to preach.

Again i understand what the overall emphasis was leading up to, as it pertained to the resurrection of the body, nevertheless, paul clearly and plainly referred back to the gospel that he had proclaimed to them previously and what it was ! You guys don`t have to agree with me, but it is as plain as day, thank you for responding though..
