Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience are defiled.
All Commentaries on Titus 1:15 Go To Titus 1
Augustine of Hippo
AD 430
But now, when you abstain for the sake of chastising the body from various kinds of food that are in themselves quite permissible, remember that “to the pure all things are pure”; don’t regard anything as impure except what unbelief has defiled; “for to the impure and unbelievers,” the apostle says, nothing is pure. But naturally, when the faithful are reducing their bodies to slavery, whatever is deducted from bodily pleasure is credited to spiritual health.
