It seems, though, that there are portals that are expressly made for copying sermons from: Göttinger Predigten, for example. They even now have a weekly Lutheran sermon in English available free of charge.
idea.de goves the theological basis for sermon reuse:
- Jesus notes in Matthew 10:8: "Freely you have received, freely give." [Note: this is, of course, the basis for the Open Access movement]
- Irenäus von Lyon (135-202) noted that a preacher is not the owner of his sermon, since God is the Creator.
- The Heidelberg theologian Rudolf Bohren records in his book on sermons, Predigtlehre: "Since there is no intellectual property in the Church of Jesus Christ, I am free to take from others what I need." He also advises that "an ungifted preacher will work much more and better if he uses a good sermon from someone else than if he fails with a self-written one."
- The Lutheran pastor for City-Church and Publicity in Esslingen, Peter Schaal-Ahlers deduces from this: Plagiarism from the pulpit contributes to quality assurance within the German Lutheran Church.
