sē̇ - les´chal ( ἐπουράνιος , epouránios , "above the sky," "heavenly"): Peculiar to Paul's majestic argument on the resurrection: celestial verses terrestrial bodies ( 1 Corinthians 15:40 ) with reference possibly to sun and moon, etc., but more probably to the bodies of angels in distinction from those of beasts and mortal men (compare Christ's words,  Matthew 22:30;  Luke 20:36 ); including also doubtless in the apostle's thought the resurrection-body of Jesus and of the saints already taken-into glory. Light is thrown on its meaning by the rendering of the same Greek original as "heavenly places" ( Ephesians 1:3 ,  Ephesians 1:20;  Ephesians 2:6;  Ephesians 3:10 ); "heavenly" ( 1 Corinthians 15:48 ). Hence, "celestial" as used by Paul indicates the soul's continued life beyond the grave, the spiritual body of the redeemed in heaven, who, in Christ, have put on immortality.
