Union with Christ — Dying and Rising in Romans 6

Sanctification flows from union with Christ. Rom 6:1-11 argues that those baptized into Christ were baptized into his death, so that "we too might walk in newness of life." Sin's dominion is broken because the believer has died and risen with Christ. Calvin made union with Christ the center of applied salvation, holding justification and sanctification to be distinct but inseparable gifts received in the one Christ. The same union grounds the Catechism's theology of life in Christ and the Eastern vision of the sharing in the divine life that Athanasius described. Owen developed the believer's mortification of sin from this union. The baptismal logic of 6:3-4 connects to the Great Commission of Matt 28:19 and to the new-creation theme of Rom 8:1-4, where there is now "no condemnation." Sanctification is the outworking of a gift already given.
