What is Reformed worship? It’s none other than worship recovered by the 16th century Reformers such as Luther, Calvin and Bucer, after they realized that the medieval church had strayed far from Biblical worship.
Does the Roman church exhibit any of these three marks? Maybe some, maybe sometimes. For sure, the true gospel of justification by faith alone in Christ alone by grace alone is not preached. Does the Roman church properly administer the sacraments in believing the doctrine of transubstantiation and baptismal regeneration? No. Does the Roman church exercise discipline among its clergy and people? We know it certainly does not.
