There is nothing un-Catholic about the moral pragmatism which is humanism.  Indeed, I would call God a practical humanist and not thinking of God that way is to exercise an unhealthy amount of moral pietousness.  Of course, there is no danger of humanism from the Trump Administration.  The key question is whether the Cabinet Secretaries allow themselves to be informed by legal advice from the permanent government.  Unless they actively work against it, there are many more SES member and high level managers who have a commitment to enforcing the law - which is the governmental substitute to the will of the shareholders.  If they become "captured" in that way, they will mostly behave - although they may have fights with the White House.  If they do not, we are about to have one scandal after another for the next four years.
