The entire article by Webster is very good; I just wanted to highlight this helpful chart, which shows the similarity between the Roman Catholic system of salvation and justification with the Judaizers of the book of Galatians, that Paul says twice are accursed for teaching a false gospel (Galatians 1:6-9; 2:4; 2:21), because they added the merit of good works to Christ's final work of redemption on the cross, as more conditions for justification. Man's responsibility is faith alone in Christ alone. Good works are the necessary result of true faith and justification, (Ephesians 2:10; James 2:14-26), but good works are not conditions that one must fulfill in order to earn one's final justification.
Note: I had trouble getting the chart to come out exactly right; but I guess this is close enough.
