This is a really fascinating read that will get ignored by a media so very invested in portraying Pope Francis as the great progressive liberator.
The Pope and Russian Patriarch of the Russian Orthodox Church met for the first time since the Great Schism in 1054. Their joint statement spends more words on the growing persecution of Christians from Islam and secular/anti-family tendencies than anything else. Read, for example, paragraph 15:
At the same time, we are concerned about the situation in many countries in which Christians are increasingly confronted by restrictions to religious freedom, to the right to witness to one’s convictions and to live in conformity with them. In particular, we observe that the transformation of some countries into secularized societies, estranged from all reference to God and to His truth, constitutes a grave threat to religious freedom. It is a source of concern for us that there is a current curtailment of the rights of Christians, if not their outright discrimination, when certain political forces, guided by an often very aggressive secularist ideology, seek to relegate them to the margins of public life.
The statement is a flat out rejection of gay marriage and also notes that as secularism increasing, Christian persecution increases. It is not just Islam.
As I have said before, the things of the world hate the things of God. Islam and secularism are just two sides of the same world oriented coin. Neither is derived from the Creator, but from creation.
