most U.S. Evangelical Christians

Yup. Most evangelical Christians elsewhere, too, at least in principle (I suspect the reward-and-punishment view of salvation and damnation is hard to eradicate altogether). But evangelical Christians are not the only Christians, and in 12th-century England -- the setting for the quotation above -- there were no evangelicals as such.

This seems to me to be a response [...]

If you mean the original quotation: no, it's set in the 12th century. If you mean the belief among evangelicals that salvation is dependent on faith and affiliation rather than on good versus bad actions: no, that's been central to evangelicalism since evangelicalism existed, and widely believed by Protestants since Protestantism existed. (I'm not sure about the history of the idea pre-Reformation, but I bet it cropped up from time to time.)
