Obviously, it is not as clear as you seem to think. I think what is needed is for you to define what you mean by “the procreative element of marriage” and to do so explicitly. What I understand by the term is that the marriage is capable of producing children, at least in theory (since infertile couples and elderly people are also deemed by the Church to be sufficiently theoretically procreative to be allowed to marry). Incestuous heterosexual sexual relations are clearly capable of doing so—there are people walking around who are living proof. You seem to understand it to mean something else entirely and for the life of me I can’t figure out what that understanding is.
Not careful enough, evidently. You explicitly said “The reason same-sex unions are unacceptable to a Catholic** is because they contradict the procreative element of marriage**. Incest (even consentual) is wrong for the same reason.” Not “one of the reasons” or “part of the reason” but “the reason”. Not once, but twice.
Last first:
My words, “they contradict the procreative element of marriage,” in no way indicate that this is the only element of marital relations that should exist. If I’m arrested for “violating speeding laws,” that in no way means that those laws are the only reason for being arrested, or that abiding by speeding laws is sufficient to be totally law-abiding.
Do you get that when someone says, “i was arrested for violating speeding laws,” and then, “so-and-so was arrested for the same reason,” that that
doesn’t imply that there are no other law-breaking acts?
When I said “Incest is wrong for the same reason,”
the means I’ve been addressing one specific reason, which is sufficient to amount to making relations wrong. If you feel I wasn’t clear, I’ll be clear now: the procreative element of marital relations is
not the only necessary element of marital relations (there is the loving, unifying element as well). Its deliberate violation makes the relations wrong; this doesn’t mean that not violating them makes them right, anymore than not speeding means you’re not breaking *any *law.
Now, for your second disagreement, I assert that incest is by its nature a faulty way of conceiving. You disagree? I don’t mean that incest
cannot result in offspring, but that the malformations that are more likely to result by the very
nature of these relations make it a wrong method of conceiving.
Peace.
