Why do you call this a "cheap shot?"
1.Because Sola Scriptura is one of the 5 solas of the reformation.
2.The comment was added by the poster, and doesn't appear in the original article or its headline.
3.It appears that the original writer had not been exposed to any of the reformed bodies - she turned to Rome because they had a written catechism, but she makes no mention of having been exposed to the confessions and catechisms of the reformed bodies, meaning it is unlikely anything in the theology of Luther or Calvin lead her to Rome.
I will concede that my use of 'Calvinists' in my reply was too narrow; I should have used 'Reformed' to have included the Lutherans as well.
