The way of purging sins by the blood of Christ is mysterious. There is no discerning of its glory but by spiritual light,—no experience of its power but by faith. Hence it is despised and neglected by the most, that yet outwardly profess the doctrine of the gospel. Men generally think there are a thousand better ways for the purging of sin than this by the blood of Christ, which they cannot understand. Wherefore, having lost the substance of this truth, and all experience of its power, to retain the use of its name, they have made sundry little images of it,—creeping things,—whereunto they ascribe the power of purging sin; such as holy water, pilgrimages, disciplines, masses, and various commutations. But they quickly found, by experience, that these things would neither purify the heart, nor pacify the consciences of sinners.
