1 Corinthians 15:22-25 (ESV)
For as in Adam all die, so also in Christ shall all be made alive. But each in his own order: Christ the firstfruits, then at his coming those who belong to Christ. Then comes the end, when he delivers the kingdom to God the Father after destroying every rule and every authority and power. For he must reign until he has put all his enemies under his feet.
I assume this refers to when Christ destroyed death, the last enemy, which is in the past.
So do Preterists say that after 70AD "the end" came and Jesus ceased to reign so that God might be all in all?
