One of the key doctrines recovered in the Reformation was that of the priesthood of all believers. What that resulted in was an increased fervor for piety. Calvin’s original (very catchy) title of the 1536 edition of The Institutes was: The Institutes of Christian Religion, Containing almost the Whole Sum of Piety and Whatever It is Necessary to Know in the Doctrine of Salvation. A Work Very Well Worth Reading by All Persons Zealous for Piety, and Lately Published. The Reformation restored a biblical understanding of fellowship with God to the individual believer, and thus recovered true fellowship between believers as well. God wants to speak to us, in His Word by His Son (Heb. 1:1-3), and God wants us to speak to Him. In other words, God wants to be with us.
