The great error of Amoris Laetitia is that it condones and attempts to justify sexual mortal sins; ignoring the radical depravity of it, excusing it, and even acquiescing to it.
It is like claiming (despite the obvious fact) that the prodigal son never left home, even when he did; that the father should welcome back the son even while the son is still in a far away land divulging his dissolute life. A contradiction. How can you welcome one while he is obstinate in his refusa to return, who has not converted: i.e., never yet "returning to himself" (
Luke 15:17).

1 Corinthians 6. One cannot be in communion with Christ and with a harlot at the same time. To say so would be
proportionalism, a moral theory clearly condemned by Veritatis Splendor.
