Acts 9:7 says that the men around Paul “stood speechless because they heard the voice but saw no one.” (NRSV)
In Acts 22:9 Paul says they “saw the light but did not hear the voice of the one who was speaking to me.”
Is this a formal contradiction, or merely a superficial contradiction that can be harmonized? Robert Bowman summarizes[1]:
“Evidently Luke [the author of Acts] means to convey that Paul’s companions saw a light and heard the sound of someone’s voice coming from the light, but only Paul saw the person in the light and heard the words spoken by the voice of that person. This explanation is reasonable, plausible, consistent with the wording of the texts, and supported by contextual elements in both accounts and in the third account found in Acts 26.”
