Rejoice, and be exceedingly glad: for great is your reward in heaven: for so persecuted they the prophets who were before you.
All Commentaries on Matthew 5:12 Go To Matthew 5
Augustine of Hippo
AD 430
I do not think that it is the higher parts of this visible world that are here called heaven. For our reward, which ought to be immoveable and eternal, is not to be placed in things fleeting and temporal. But I think the expression in heaven means in the spiritual firmament, where dwells everlasting righteousness: in comparison with which a wicked soul is called earth, to which it is said when it sins, Earth you are, and unto earth you shall return. Of this heaven the apostle says, For our conversation is in heaven. Hence they who rejoice in spiritual good are conscious of that reward now; but then it will be perfected in every part, when this mortal also shall have put on immortality. For, says He, so persecuted they the prophets also which were before you. In the present case He has used persecution in a general sense, as applying alike to abusive words and to the tearing in pieces of one's reputation; and has well encouraged them by an example, because they who speak true things are wont to suffer persecution: nevertheless did not the ancient prophets on this account, through fear of persecution, give over the preaching of the truth.
