This is not about politics...the issue is the unclear theological statements he made regarding divorce and communion.
Catholics understand that God made the Holy sacrament of marriage to last forever...that a husband and wife becomes as one. When that is destroyed by divorce an investigation is conducted to determine if the marriage was or was not a holy marriage. This is done by Catholics who wish to partake in communion and or remarry ingredients in the Catholic Church.
The Pope made some statements which could be interpreted as varying from that. The fact that he is not answering suggests that he understands he made an error...he is just a man after all...and rather than say “I made an error” prefers to be corrected as this article talks about. I think it shows how on target the Catholic Church is to the biblical and traditional teachings of Christ.
The issue is actually the unclear statements he made rejecting morality and the necessity of the individual to always seek to conform himself to the moral law, in favor of situation ethics and a declaration that the morality of even an essentially evil act was contingent upon subjective factors. It is true that he did away with the Catholic concept of marriage (and indeed seems to regard cohabitation as the equivalent of marriage) but, more importantly, he attacked the whole concept of the moral law, which should be everywhere and always the same if it is to mean anything.
Of the five dubia or questions asked by the Cardinals, only one dealt with marriage and the other 4 dealt with the moral law in general.
