No, the pope is not a theistic evolutionist. To be an evolutionist one has to accept the synthesis of Julian Huxley and others, which postulates the randomness that the pope rejects. And while he admires Theilhard de Chardin, he rejects his theology which tries to incorporate evolution into Catholicism as other Jesuits try to incorporate Marxism.
He may reject randomness, but he certainly does not reject evolution per se, and he apparently rejects all forms of instantaneous creation.

Hence my point that he is a "theistic" evolutionist--one who believes that evolution is guided by Divine Providence. But he still rejects the facticity of the first eleven chapters of Genesis.
