In the sacraments your God, Christ himself, deals, speaks, and works with you through the priest. His are not the works and words of man. In the sacraments God himself grants you all the blessings we just mentioned in connection with Christ. God wants the sacraments to be a sign and testimony that Christ’s life has taken your death, his obedience your sin, his love your hell, upon themselves and overcome them. Moreover, through the same sacraments you are included and made one with all the saints. You thereby enter into the true communion of saints so that they die with you in Christ, bear sin, and vanquish hell.
--Martin Luther, LW42, Devotional Writings
