The Dreaded Exhortation Draws Near

It has been announced that the much-dreaded post-synodal exhortation (called Amoris Laetitia, "Joye of Love") will be published April 8th.  All reports are that the thing will probably be much worse than originally anticipated.  It will be trumpeted by Cardinals Baldisseri and Schonborn - both progressives.  Cardinal Kasper, another progressive, has already promised that this thing will be "revolutionary".  Sadly, I believe him.

Here are reports from Eponymous Flower and two from Catholic Family News (here and here).  Take a look at these.  For now, let's focus on the one from Eponymous Flower, for in it is a phrase that I find quite curious: "The letter is the result of double Synod on marriage and family, which took place in 2014 and, 2015. It is to replace the Apostolic Exhortation Familiaris Consortio  (1981) by Pope John Paul II."

Replace?  This is the first time I ever heard of a predecessor's writings being replaced.  I can understand "being supplemented" or even "being clarified", but this makes it sound like the writings of a previous pontiff (and a canonized one at that) is being declared obsolete.  What gives with that?

The first CFN article states that we faithful Catholics must pray, learn our doctrine and be prepared to publicly resist the approaching menace.
