A corporate resolution is easily fabricated and probably needs some further verification to ensure that it accurately represents the will of the governing body of the organization (if there is, indeed, such a governing body). Marginally better because it's a public record would be a copy of a corporate filing in your state capital, often accessible on the Web. At least it shows that someone filed the paperwork. But with religious organizations, it's often difficult to know whether a state filing is required.
