John Vujicic agrees with the interpretation above and supports it with two further observations. First, he notes that after receiving the vision, Peter did not eat anything. But, Vujicic writes, "In the sheet were also so called CLEAN animals. Peter could have at least selected some sheep or cattle and killed but he didn’t." Second, according to Vujicic, the reason Peter didn't simply take up and eat a "clean" animal was because Peter was in fact a vegetarian. Peter is reported as describing himself as a vegetarian in the Clementine Homilies. This last point will be unconvincing to many Christians, because the Clementine Homilies are not canonical literature.
