This is really important.
I’ve been waiting for a Dominican well-versed in Thomas to examine the claim that Amoris laetitia is a “Thomistic” document and/or that it makes good use of the Angelic Doctor’s words.
At LifeSite find an examination by Father Thomas Crean, O.P., who has serious credentials.
I think what he wrote settles the issue.
I suggest that you print it out.
