In this video, Michael Reeves explains why the Reformation is not over.
The Reformation is not over and cannot be over. The first reason it’s not over is because the Roman Catholic Church has not been reformed. Rome, by her own catechism and statements, still repudiates justification by faith alone, and therefore the matter of the Reformation has not been resolved.
Furthermore, those churches that would not call themselves Roman Catholic needed to be ongoingly reformed because reformation is not something that can be settled. Reformation is about the church purifying herself by the Word of God continually. There is never some acceptably pure level.
So, reformation is an ongoing thing. And that means that reformation cannot be over until Christ returns, because reformation is about chasing that purity that Christ wants for His church. And we have not reached that and we will not reach that until He returns.
