The impeccability of Christ is an important, though debated point. It involves not only the sinlessness of our savior, but whether it was possible for him to sin. As we consider the issue, we turn to F. W. Kremer's article, "The Impeccability of the Lord Jesus Christ" published in Reformed Quarterly Review, Volume 26, April 1879.

We discuss the tendency to consider Christ's humanity independently of his divinity. It's not merely that people recognize the natures are distinct, but that they implicitly acknowledge that his humanity can be abstracted from his divinity. In the abstract, we could acknowledge that Jesus's human nature had the capability of sinning. For example, his body was physically capable of taking a sword and murdering someone. But we cannot consider Christ's human nature in the abstract. He is the second person of the trinity who has assumed a true body and a reasonable soul. Sin involves a moral agent. Does the human nature of Christ constitute a full moral agent apart from the person of the son? This also raises serious issues regarding God's decree. Throughout the episode, we maintain that if it was possible for Christ to sin, it was possible for Christ to fail.
