That is not the same Gospel that the RCC preaches.
Not quite. We believe that works are a PRODUCT of being in-dwelt with the Holy Spirit, not a separate way to Heaven. It is part of the sanctification process, not the justified — which only occurs once (according to Scripture) when one comes to faith in Christ.
More precisely, historically they overall believed that one is justified by faith alone - that being the instrumental means of procurement - but not by a faith that was alone. And this was and is evidenced in evangelicals manifesting more commitment and conservative moral views than RCs. http://www.peacebyjesus.com/RC-Stats_vs._Evang.html Glory to God for those who do.
