You are the salt of the earth: but if the salt has lost its savor, how shall it be salted? it is thereafter good for nothing, but to be cast out, and to be trodden under foot of men.
All Commentaries on Matthew 5:13 Go To Matthew 5
Cyril of Alexandria
AD 444
He calls “salt” the frame of mind that is filled with the apostolic word, which is full of understanding. When it has been sown in our souls, it allows the word of wisdom to dwell in us. It has been compared with salt because of salt’s good taste and delightfulness. For without salt neither bread nor fish is edible. So too without the apostles’ understanding and instruction, every soul is dull and unwholesome and unpleasant to God.
