Boanerges said to J Edwards:
Joe searching around I found this document at the WELS Q&A site Christ's Temptation seems what Speratus is spouting is standard Lutheran view regarding Christ. So as my old man used to say you can lead a horse to water.

WELS Q&A quotes an Anglican scholar and a Lutheran dogmatician and states, "The quoting of Alfred Edersheim and Franz Pieper above was done in part to assure you that our position is by no means only a WELS one. Nor is it limited to Lutherans. It is biblical."

Significantly, WELS Q&A does not quote the Book of Concord or even an official WELS doctrinal statement. As much as I agree with Impeccability, I can't say that Impeccability is explicitly taught in the Lutheran Confessions.

J Edward answers
Oh, I know his heritage, however, his heritage is not embracing the Scripture and thus my appeal to Ad Fontes, Ad Fontes, Speratus.

Sola Scriptura, J Edwards. Scripture is the only source of doctrine.

You appeal to Chalcedon and Westminster. However, these confessions say nothing regarding the Peccability of Christ. Can you find one orthodox early church or Reformation confession that explicitly endorses Peccability?
