Now, I'm a Christian, but I'm not hyperspiritual and I don't buy what Pat Robertson is saying.
The pact with Satan is an unsubstantiated rumor from Haiti's past. A World Net Daily article quotes Haitian Christian minister, Jean R. Gelin PHD, who has studied the issue (emphasis mine):
. . . such a strong affirmation should be based on solid historical and scriptural ground. But, although the satanic pact idea is by far the most popular explanation for Haiti's birth as a free nation, especially among Christian missionaries and some Haitian church leaders, it is nothing more than a fantastic opinion that ultimately dissipates upon close examination.
This really bugs me. Aside from the inherent cruelty of the statement (that being the idea that Haiti brought this on itself), when a high profile minister such as Robertson publicly cites this as a reason for the earthquake, it threatens the credibility of every Christian minister. How can we expect the world to take our claims of eternal life or damnation seriously when we are seen as giving credence to legends and rumors?
