Who says Ananias’ words were impeachable? Paul says that is what he said, and, though hearsay, Ananias did say that. But that does not have any sense of imparting a contradiction to the facts of Acts 9, does it? Nor is there any implication of what he said as being inspired. Even Peter said a lot of things that were uninspired by God, though the telling of the scenario in which he lied was inspired.
You impeached Ananias when you wrote: "Acts 22:16 is an iffy procedure proposed by Ananias before Paul’s formulation of his own gospel as taught personally by the Lord Jesus Christ. Ananias’ words were not necessarily inspired words, although the history of him saying them is inspired and inerrant."
Where does it say in Acts 9 that Paul’s sins were forgiven BEFORE he was baptized??
