The following study seeks to investigate the impeccability of Christ from a historical/theological position. Two camps emerge on either side of the debate: Those who hold to the posse non peccare view, which is to say, ability not to sin, otherwise known as the peccability view and those who hold to the non posse peccare view, which is to say inability to sin, otherwise known as the impeccability view. While both camps affirm the sinless perfection of Christ, they oppose each other in whether as fully human He could have sinned if He wanted to. It boils down to a case of 'could have but did not' or 'did not because He could not have'. It is the view of this thesis that the non posse peccare view squares with both historical and biblical theology.
