The resurrection of the dead - That is, the resurrection of those who, having died in the Lord, rise to glory and honor; and hence St. Paul uses a peculiar word which occurs no where else in the New Testament, εξαναστασις. The words, as they stand in the best MSS., are as follow: εις την εξαναστασιν την εκ νεκρων, to that resurrection which is of the dead. This glorious resurrection, and perhaps peculiarly glorious in the case of martyrs, is that to which St. Paul aspired. The word αναστασις signifies the resurrection in general, both of the just and unjust; εξαναστασις may signify that of the blessed only.
