And I will give unto you the keys of the kingdom of heaven: and whatsoever you shall bind on earth shall be what has been bound in heaven: and whatsoever you shall loose on earth shall be what has been loosed in heaven.
All Commentaries on Matthew 16:19 Go To Matthew 16
Epiphanius the Latin
AD 403
For Christ is a rock which is never disturbed or worn away. Therefore Peter gladly received his name from Christ to signify the established and unshaken faith of the church …. The devil is the gateway of death who always hastens to stir up against the holy church calamities and temptations and persecutions. But the faith of the apostle, which was founded upon the rock of Christ, abides always unconquered and unshaken. And the very keys of the kingdom of the heavens have been handed down so that one whom he has bound on earth has been bound in heaven, and one whom he has set free on earth he has also set free in heaven.
