However, today's post about news vs fake news is the best summary of all those controversies that I have seen.
here is the part about the slight of hand on marriage:
Fake news: The Pope holds two Synods on the Family designed to decide whether Catholic teaching has "developed". Cardinal Baldisseri steals copies of the "Five cardinals" book that are being sent out to participants. After the Synod - or, in fact mostly before it - the Pope's ghostwriters produce a muddled document called Amoris Laetitia ("The Joy of Sex"), which is deliberately ambiguous and bears little relationship to what the Synod has decided.
True news: Cardinal Kasper goes to the Pope and says "Let's have a Synod to celebrate the joy of Christian marriage, as preached by the Church for the last 2000 years."
Hijacking a meeting to push a radical agenda is a common political tactic, especially when working with nice folks who don't want to seem so impolite to criticize.
