Protestant Era of Great Apostasy - I want to comment on the contention that "grace alone" doesn't emphasize the need for works enough. Every Bible-believing church I have been a member of has firmly believed that "grace alone" will never be without good works. The difference as I understand it is that we believe good works are necessarily the fruit of the Holy Spirit's work in our hearts. While we battle/struggle, it is because of the Holy Spirit not allowing any true believer to remain the way they are when they first believe. The point the early church made against the Jews who made works a condition of salvation was that salvation then becomes something you earn by keeping rules, not something you are given as a gift from God. Jesus said "Without me you can do nothing", so as we have a relationship with Jesus, He empowers us by the Holy Spirit to bear abundant fruit of the Spirit and to do many good works.
