(6) And I will give unto thee the (n) keys of the kingdom of heaven: and whatsoever thou shalt (o) bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.
(6) The authority of the Church is from God.
(n) A metaphor taken from stewards who carry the keys: and here is set forth the power of the ministers of the word, as (Isaiah 22:22) says, and that power is common to all ministers, as (Matthew 18:18) says, and therefore the ministry of the gospel may rightly be called the key of the kingdom of heaven.
(o) They are bound whose sins are retained; heaven is shut against them, because they do not receive Christ by faith: on the other hand, how happy are they to whom heaven is open, who embrace Christ and are delivered by him, and become fellow heirs with him!
