I would respectfully disagree.
Extramarital heterosexual intercourse is a sin, but it is not disordered.
Sure it's disordered. Any sin is disordered. Extramarital intercourse is disordered in fewer ways than sodomy, but it's still disordered.
But disordered in the sense of outside of God's plan for sex in marriage; out-of-order; often inordinate.
Though I see many statements on adultery; I have been unable to find anything, said by Jesus or attributed to him that states premarital sex is a sin.
Yes I know Augustine and Aquinas have spoken on the issue; but where is it written that Jesus spoke on the issue?
I agree. Heterosexual intercourse is natural and normal in the physical sense while homosexual activity is not. This is obviously the meaning of the text in the Catechism, which does not refer to adultery or fornication as "disordered". (If I am wrong, please cite the text.)
I think it is a mistake to extend the term "disordered" to include any offense against God -- in the attempt to avoid offending homosexuals -- because it creates the very confusion the Cardinal would avoid.
Sex outside of marriage is disordered. There is a solution for that, get married. However being attracted to a member of the opposite sex is not disordered (assuming it is appropriate and legal) while being attracted to a member of the same sex is.
Do you have the Ten Commandments in your Bible?
How about “Thou shall not covet thy neighbor’s wife.”
It is disorderly. The many cases where spouses simply walk out is not even treated as a breach of contract any more. A bond that ought to be as strong as that bond between a parent and child is broken. Abandonment. The result is turmoil in the lives of persons and in society.
