The Spirit Does Not Contradict the Gospel

But in promising it, of what sort did he declare his Spirit would be? One that would speak not from himself but would suggest to and instill into their minds what he had handed on through the Word [John 16:13]. Therefore the Spirit, promised to us, has not the task of inventing new and unheard-of revelations, or of forging a new kind of doctrine, to lead us away from the received doctrine of the gospel, but of sealing our minds with that very doctrine which is commended by the gospel. ~ Institutes of the Christian Religion

Forsaking Scripture, Men are Carried Away with Frenzy

Furthermore, those who, having forsaken Scripture, imagine some way or other of reaching God, ought to be thought of as not so much gripped by error as carried away with frenzy. For of late, certain giddy men have arisen who, with great haughtiness exalting the teaching office of the Spirit, despise all reading and laugh at the simplicity of those who, as they express it, still follow the dead and killing letter. ~ Institutes of the Christian Religion

The Sacraments & the Spirit of Faith

“Just as the light of the sun, while it invigorates a living and animated body, produces effluvia in a carcass; so it is certain that the sacraments where the Spirit of faith is not present, breathes mortiferous rather than vital odour.”

Self-Confidence & the Spirit

“There is no worse screen to block out the Spirit than confidence in our own intelligence.”
