What an excellent article. Thank you. 

"Indeed, the third part of Veritatis Splendor, entitled “Lest the Cross of Christ Be Emptied of Its Power,” warns precisely against the view that the demands of the moral life are too difficult and cannot be lived with the help of God’s grace. Chapter 8 of Amoris Laetitia appears to be exactly what St. John Paul II had in mind in writing Veritatis Splendor. It does appear to empty the cross of Christ of its power."

Discernment, accompaniment and mercy ought not lead to abandoning trust in Christ's grace. There's something very Lutheran about all this.
