As an argument for the existence of purgatory, Protestant religious philosopher [[Jerry L. Walls]]<ref>{{cite web |url=https://www.hbu.edu/Choosing-HBU/Academics/Colleges-Schools/School-of-Christian-Thought/Departments/Department-of-Philosophy/Faculty/Jeremy-Neill-(1).aspx |url-status=dead |title=Jerry Walls, PhD |publisher=HBU.edu |archive-url=https://web.archive.org/web/20150503012307/http://www.hbu.edu/Choosing-HBU/Academics/Colleges-Schools/School-of-Christian-Thought/Departments/Department-of-Philosophy/Faculty/Jeremy-Neill-(1).aspx |archive-date=2015-05-03 }}.</ref> wrote ''Purgatory: The Logic of Total Transformation'' (2012). He lists some "biblical hints of purgatory" (Mal 3:2; 2 Mac 12:41–43; Mat 12:32; 1 Cor 3:12-15) that helped give rise to the doctrine,<ref>[https://books.google.com/books?id=kFqzG3UPz3EC&dq=Walls+%22biblical+hints%22+purgatory&pg=PA11 Jerry L. Walls, ''Purgatory: The Logic of Total Transformation'' (Oxford University Press 2012), pp. 11–13]</ref> and finds its beginnings in [[Early Christianity|early Christian]] writers whom he calls "Fathers and Mothers of Purgatory".<ref>Walls, 2012, pp. 14–17</ref> Citing Le Goff, he sees the 12th century as that of the "birth of purgatory", arising as "a natural development of certain currents of thought that had been flowing for centuries",<ref>Walls, 2012, pp. 17−22</ref> and the 13th century at that of its rationalization, "purging it of its offensive popular trappings", leading to its definition by a council as the church's doctrine in 1274.<ref>Walls, 2012, pp. 22–24</ref> 

Walls does not base his belief in purgatory primarily on scripture, the Mothers and Fathers of the Church, or the [[magisterium]] (doctrinal authority) of the Catholic Church. Rather his basic argument is that, in a phrase he often uses, it "makes sense."<ref>For example, Walls,  2012, p. 71</ref> For Walls, purgatory has a [[logic]], as in the title of his book. He documents the "contrast between the satisfaction and sanctification models" of purgatory. In the satisfaction model, "the punishment of purgatory" is to satisfy God's justice. In the sanctification model, Wall writes: "Purgatory might be pictured ... as a regimen to regain one’s spiritual health and get back into moral shape."<ref>Walls, 2012, pp. 76, 90.</ref> 

In Catholic theology Walls claims that the doctrine of purgatory has "swung" between the "poles of satisfaction and sanctification" sometimes "combining both elements somewhere in the middle". He believes the sanctification model "can be affirmed by Protestants without in any way contradicting their theology" and that they may find that it "makes better sense of how the remains of sin are purged" than an instantaneous cleansing at the moment of death.<ref>Walls 2012, p. 90</ref>
