What is Christianity? by Francis Pieper

We hear from the Apostle Peter that Christians should always be ready to give a confession of the hope that is in them and to defend their faith in an ever-changing world.

Originally delivered as an address at a synod convention in 1902, Das Wesen des Christentums or What is Christianity? was written by pastor and professor Francis Pieper.

In What is Christianity: Faith and Morality Reconsidered, Pieper takes up Peter's task against those who would confess works, moral improvement, and other man-made projects over and against the confession of Christ and him crucified. He boldly confesses what it means to be a Christian and what Christianity looks like with Christ truly as the center. In so doing, Pieper equips the saints to defend and proclaim the good news of forgiveness of sins on account of Christ alone.

Pastor Philip Bartelt (translator of Pieper's presentation) says, "For Pieper, to be Lutheran meant to believe in Jesus Christ as the perfect sacrifice for sins in our stead--that Jesus was put under the law, under our sin, and under our punishment, in our stead and on our behalf, so that by faith we may enjoy perfect freedom, righteousness, and salvation."
