""struck a common theme: The church's teaching on marriage is "irreformable," based on the words of Jesus in the Gospels, & unchanged for two millennia."
AND:  "a very conservative, interpretation of previous magisterial statements against statements contained in Amoris Laetitia."
And: "a "filial correction"  AND:  "The document accused the pope of spreading heresies "

These clergy need to learn or relearn the simple truths that Jesus taught and quit looking to punish people Jesus would not punish. I'm thinking of these parables:
John 13:35: “34 A new commandment I give you: Love one another. As I have loved you
Matthew 21:8-32:  Parable of the Two Sons
Luke 15:11-32:  The Parable of the Prodigal Son

Jesus had only two commandments.  
In the two sons, the lowest people were going to heaven, if at all, before the Temple leaders.
In the Prodigal Son, the father was absolutely forgiving.

These clergy should  learn from these three teachings of Jesus.
