Gay people hate the word disordered.
It is one of the single most objectionable words used in Catholic teaching regarding homosexual acts. It was even mentioned at the Synod - as hurtful language. The use of the word disordered is one of the objections to the CDF documents regarding pastoral care of homosexual persons. It is why not a few gay-Catholics dislike Cardinal Ratzinger - Pope Benedict - simply because he was in charge at the time and responsible for updating the Catechism as well as issuing the following clarification:
Since “[i]n the discussion which followed the publication of the (aforementioned) declaration..., an overly benign interpretation was given to the homosexual condition itself, some going so far as to call it neutral or even good”, the letter goes on to clarify: “Although the particular inclination of the homosexual person is not a sin, it is a more or less strong tendency ordered towards an intrinsic moral evil; and thus the inclination itself must be seen as an objective disorder. - Some considerations ...The supreme pontiff, St. John Paul II, signed off on all of it - meaning the CDF or Ratzinger did not step outside Catholic doctrine.
In the spiritual life - which every Christian is called to - terms such as disordered and inordinate are frequently used to describe obstacles to 'our perfect union with God'. Recently, a meditation from Archbishop Luis Martinez appeared in Magnificat magazine, which may help us understand better the meaning of such terminology and the reason why it is used.
Whenever the affections of the heart are not an expansion of divine love, they are an obstacle to our perfect union with God. (an obstacle to sanctity)
Although every affection that blossoms from the love of God is holy, and increases our perfection rather than impedes it, the same is not true of any other affection that has purely human and natural roots; for from affections of this kind come forth sins, both mortal and venial.
Inordinate affections are the root of sin ...
When at any time an affection rises to the point of taking complete possession of our heart in such a way that it causes us to place our happiness and our final end in a creature, then mortal sin is committed; for mortal sin is nothing else but the triumph of an inordinate affection over the love of God.
Very often a disordered affection does not go to such an extreme, yet it can contrive to live side by side with the love of God. Then it is a species of parasite that prevents the love of God from developing in all its fullness and in all its glory. In this case, a disordered affection is the cause only of venial sins or simply imperfections, yet, in every instance, it hampers the perfect development of the love of God. - Archbishop Luis M.
