My impression is that the root cause of the resistance to "Amoris Laetitia" is religious patriarchy.  As long as the hierarchy of the Church  remains patriarchal, there is no way in the world to reconcile our doctrines of human sexuality with created reality.  The reason is that our current sacramental theology is contaminated with ancient/modern versions of "patriarchal gender theory" (i.e., the sex/gender binary, male headship, and complementarian stereotypes).  The confusion is in part due to a biased patriarchal interpretation of St John Paul II's "Theology of the Body."  This is the most formidable obstacle to the "new evangelization."  May I share my petition to Pope Francis about this unavoidable issue:
