I have avoided posting in the recent flurry of atonement threads simply because they do not interest me. However, I think it is helpful to define what Calvinism is. One would think the Reformed view of soteriology is understood by all, but apparently (based on what I have read on this board) that is not the case.
If you ask a Reformed paedobaptist what qualifies as Calvinism, it will be difficult for them to separate Calvinism from the whole of their theology. In other words, they consider their view on baptism to be intrinsically linked to soteriology. While Reformed or Particular Baptists do believe all aspects of theology are part of a larger whole, not every doctrine has to fall just right in order for Calvinistic soteriology to be true. For example, some esteemed brothers on this board do not believe in penal substitution. However, some of these brothers affirm all five Solas. Speaking as a Reformed Baptist, such brothers would be considered Calvinists because in the Reformed Baptist schema Calvinism is defined solely by its belief in Sola Gratia, Sola Fide, Sola Scriptura, Solus Christus, and Soli Deo Gloria. This is a narrow view of Calvinism, limiting it to these five specific things. Some Christians have a larger view of Calvinism and, therefore, they reject it. The cannot separate the Five Solas from penal substitution or infant baptism. They see all those things as being part and parcel, so they reject the whole thing.
When Charles Spurgeon wrote his "A Defense of Calvinism", his focus was not on the Reformed paedobaptist view of John Calvin and John Knox. His focus was on the Five Solas and the debate on free will. He added nothing more to his view of Calvinism. Now, it would be fair to say that the Particular Baptists of the 17th-century, as well as Charles Spurgeon, co-opted the term "Calvinist" for themselves. They discarded the parts of Calvin's theology that were not compatible with Baptist theology while retaining Calvin's excellent conclusions on predestination and election. Among Baptists, if Calvinism is nothing more than belief in the Five Solas of the Reformation, then anyone who affirms them is a Calvinist. To be sure, Calvinists who reject penal substitution are a minority, but their atonement view does not negate their belief in the Five Solas. I will add that Amyraldianism is a rejection of definite atonement and falls outside of Calvinism. Ergo, in spite of their passionate insistence, Amyraldians are not Calvinists.
