Jerome, on Titus 1:15

“All things are clean to the clean: but to them that are defiled, and to unbelievers, nothing is clean: but both their mind and their conscience are defiled.”

“"All things are clean to the clean, but to the unclean and unbelieving nothing is clean; instead, both their mind and their conscience are corrupted." For he had said earlier: "For there are many rebellious people who deceive others with their empty talk and false teaching. This is especially true of those who insist on circumcision for salvation. They must be silenced, because they are turning whole families away from the truth by their false teaching. And they do it only for money." So he is telling Titus to sharply rebuke them, so that their faith will be healthy and they will not waste their time in endless discussion of myths and spiritual pedigrees. This kind of talk only leads to meaningless speculations, which don't help people live a life of faith in God. The Bible clearly states that all things are clean to those who believe in Jesus Christ and know that everything God created is good. But to those who are defiled by sin and unbelief, nothing is clean; in fact, both their mind and their conscience are corrupted. Therefore, even things that are clean by nature become unclean to them. This is not because there is anything inherently unclean or clean, but because of the kind of people who eat them. So, the clean remain clean for the clean, and the unclean become defiled for those who are defiled. Otherwise, even the unbelievers and defiled do not benefit from the bread of blessing and the Lord's cup; for whoever eats of that bread and drinks from the cup unworthily eats and drinks judgment upon themselves (1 Cor. 11). Everything has been cleansed by the coming of Christ. We cannot partake of what He has purified. But let us consider that in handling this, we do not give occasion to that heresy which, according to the Apocalypse (Chapter 2) and even the Apostle Paul himself writing to the Corinthians, thinks that it is right to eat of things offered to idols because all things are clean to the clean (1 Cor. 8). For the Apostle did not intend to discuss those things which are sacrificed to demons, but rather those who, according to the discipline of the abolished Law, regarded some things as clean and others as unclean. For we cannot partake of the Lord's table and the table of demons: nor can we drink the cup of the Lord and the cup of demons at the same time (1 Cor. 10:20-21). Therefore, it is up to us to eat clean or unclean. For if we are clean, then the creature is clean for us. But if we are unclean and faithless, then all things become common to us, whether through the heresy that dwells in our hearts or through the consciousness of sins. Moreover, if our conscience does not condemn us, and we have confidence in God's mercy, then we will pray with our spirit and with our mind, we will sing praises with our spirit and with our mind (1 Corinthians 14), and we will be far from those of whom it is now written: "Their mind and conscience are defiled."”
