The Greek noun exanastasis (ἐξανάστασις) means resurrection — specifically, the resurrection out from among the dead. The ex- prefix distinguishes it from simple anastasis: this is the resurrection in which the righteous rise out from among the remaining dead — the first resurrection. It appears once in the New Testament.
In Philippians 3:10–11, Paul writes that he strives to attain the exanastasis ton nekron — the out-resurrection from among the dead. The deliberate use of exanastasis signals a specific, selective resurrection — not the general resurrection of all, but the first resurrection of the righteous in Christ. This was Paul's consuming goal, and it gives resurrection ethics its eschatological urgency.
