And I will give to thee the keys of the kingdom of heaven. And whatsoever thou shalt bind upon earth, it shall be bound also in heaven: and whatsoever thou shalt loose upon earth, it shall be loosed also in heaven.
Origen
Let him then be without blame who binds or looses another, that he may be found worthy to bind or loose in heaven. Moreover, to him who shall be able by his virtues to shut the gates of hell, are given in reward the keys of the kingdom of heaven. For every kind of virtue when any has begun to practise it, as it were opens itself before Him, the Lord, namely, opening it through His grace, so that the same virtue is found to be both the gate, and the key of the gate. But it may be that each virtue is itself the kingdom of heaven.
