Well historically, salvation had always been both a works and faith thing, it wasn't until martin luther preposed his doctrines, which led to the split we all know and love, that it became about faith vs works really sure people argued it in the church before then.
but it wasn't until luther, then calvin came along that it caused the split
personally i think only salvation without works is pointless in the life and works without a meaning are just as pointless, both are needed, Its when you define eather as more importiant that you lose sight of the reasons you do things
