I don't think referring to parrots or sheep is appropriate.
I told Kevin where he could find the "Gospel" which was the term he used. And then I briefly elaborated on what the term refers to. I gave a summary of Gospels (plus a little of Acts) and an suggestion that he could read it for himself if he felt it was important or urgent.
Reading it for yourself from the Bible certainly has less of a "slant" or "interpretation" (if you will) than hearing the person speaking at church.
