Arc 4 is fully fan translated, you can find it by just looking it up. Arc 5 is halway translated, as the translator stopped translating it. Arc 6 only have portions translated. The summary on Natsuki Subaru/Synopsis page is pretty accurate, so you can read that.

The Divine Protection of Sword Saint is the Divine Protection that the Sword Saint holds. The wishing for all divine protections is Reinhard's unique ability, none of the former Sword Saint had that power. By the way, it isn't called Divine Protection of Wish, that's just a fan name for his wishing ability.
