Below is a sampling from a young but obviously erudite theologian from New Orleans Baptist Theological Seminary, Dr. Blake Newsom. In pursuing the question, What is the Gospel?, Newsom cuts through the literary wasteland in evangelical circles that tends to see all issues as "gospel issues" by flatly concluding "If everything is the gospel, then nothing is the gospel." Here's the entire contextual snippet:
Of concern to this writer is that the gospel has become a buzzword in Evangelicalism. As is often the case with buzzwords, they lose their core identity and meaning due to their overuse in books, conversations, and retweets of pithy statements. The word gospel has become a catch-all term that captures attention. Since every Christian theme or doctrine seems related and attached to the gospel, every Christian theme or doctrine is mistakenly regarded as synonymous with the gospel. Consequently, all of the important doctrines in Christianity become the gospel, including (but not limited to) creation, theology proper, Scripture, the Trinity, prayer, angels and demons, anthropology, soteriology, pneumatology, ecclesiology, and eschatology. Again, do not misunderstand my claim. The gospel is inextricably linked to all elements, themes, and doctrines of Christianity; however, all elements, themes, and doctrines of Christianity are not the gospel and should not be posited as synonymous with the gospel. Holding such a view complicates a legitimate understanding of the gospel. If everything is the gospel, then nothing is the gospel (pp. 4-5).
So far as I am concerned, Newsom effectively dismantles the trendy but thoroughly inadequate--not to mention confusing--usage of "gospel this" and "gospel that" even in Southern Baptist sub-culture.
I think you'll find Newsom's entire piece well worth the time it takes to absorb his point.
