How did this quote slip through...?

A quote from Warfield that should shock high church Reformed into some degree of biblical understanding but probably won't. (High church Reformed, not to mention others either wholly given over to the Beast, or merely keeping a little of the fat and darkness of the Beast still on their plate):

“Previously, men had looked to the Church for all the trustworthy knowledge of God obtainable, and as well for all the communications of grace accessible. Calvin taught them that neither function has been committed to the Church, but God the Holy Spirit has retained both in His own hands and confers both knowledge of God and communion with God on whom He will.” - B.
