An interesting thought from Luther’s sermon for New Year’s Day in the Church Postil:
For when death fell on Him and killed Him, and yet had no right or case against Him, and He willingly and innocently submitted and let Himself be killed, then death became liable to Him, did Him wrong and sinned against Him, and itself spoiled everything, so that Christ has an honest claim against it. Now the wrong of which [death] became guilty toward Him is so great that death can never pay nor atone for it. Therefore, it must be subject to Christ and in His power forever, and so death is overcome and put to death in Christ. (Luther’s Works 76 [CPH, 2013], 45)
Again, this fits beautifully with the centrality of the baptismal union: all things are subjected to Christ, for the Church (Eph. 1:22). Apart from Christ, death rules over my body. In Christ, death is subject to me, because it is subject to Him and I am in Him.
