It's difficult to decide. I've recently been of the opinion that Benedict XVI had already surpassed JPII in treachery, but then I found this reference to the Talmud made by JPII during his General Audience of Wednesday 12 April 2000.
Here JPII seems to make reference to the female Shekinah-Matronit aspect of the hermaphrodite god of Judaism:
"Also significant is an ancient Jewish comment on the passage in Genesis (cf. 1: 2) which describes the Spirit moving over the primeval waters with motherly tenderness: 'The Spirit of God was moving over the face of the waters like a dove that hovers over her little ones without touching them' (Talmud, Hagigah 15a)." (John Paul II, Wednesday, 12 April 2000)
JPII seems to be signaling a key occult gnosis which has been preserved through the centuries within rabbinic Judaism, that of the hermaphrodite god.
JPII clearly intends to portray the Holy Spirit as feminine, but Genesis 1;2 offers no basis for such strangeness. Enter the Talmud and it's intricate fables, erroneous abuses, and unheard-of stupidities (Pope Innocent IV) and there is found support for the notion of a feminine Holy Spirit which JPII sought to impart.
Yes, the image of JPII kissing the Koran is seared into the minds of many Catholics, but that was merely a photo op, as treacherous as it was. I suspect that in reality he had a far more substantial relationship with the Talmud.
