by faith alone — there are Unitarians, Swedenborgians, even some Evangelicals (can’t remember which off hand, but some freepers belong to these and pointed it out) which refute that.
Then those folks aren’t historic Protestants either. By the way, the word Evangelical, much like Protestant or Christian, has been stripped of its historic meaning. Rob Bell is labeled Evangelical and so am I. Even so I probably have less in common with Rob than I do with some conservative Catholics, yet I hold essentially the same view of the RCC, popery and Catholic priesthood as Luther, Calvin, Knox, Edwards and Spurgeon.
Scripture clearly teaches that salvation is by grace alone through faith alone. Erasmus correctly recognized that was the heart of Luther’s protest. Historic Protestants were united on this point.
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God.” (Ephesians 2:8)
