This is still not an explaination of cheat shot.
The comment was added by the poster, and doesn't appear in the original article or its headline.
Same as above.
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 see no basis for such a conclusion. Clearly her exposure to Bible-only advocates implies non-catholic influence.
Sola Scriptura does not mean Bible-only.
Perhaps, then, you can get someone to explain it to you on your level.
