Melinda Penner of Stand to Reason gave the following reaction:
It's unfortunate that Pat Robertson thinks he has insight into God's hidden actions to claim that the Haiti earthquake is a consequence of a pact with the Devil Hatians made two centuries ago. He may be right in some respects, like the evil nature of voodoo, but drawing a cause and effect requires insight into God's intentions that we have no reason to believe Robertson has. God has judged nations, we know from His revelation, but that provides no grounds at all to interpret any specific disaster as judgment. Earthquakes may be a natural phenomenon God could use, but it doesn't follow at all that any particular earthquake is a judgment of God's unless He tells us. Jeremiah 29:23 expresses God's offense at an instance of falsely speaking on His behalf. This shows us that it's a serious thing to claim to speak for God, and we should only do so on the proper authority of His revelation. Robertson provides us claim or reason to think he has that knowledge. This is his own speculation. Despite the compassion Robertson also expressed in his claim, which is no doubt sincere and he is praying for these suffering people, he was out of line in any attempt to speak for God in this instance.
