Boys have a… and girls have a …
Yes, so I’ve heard.
I know the Church maintains that there are two genders, and that everyone, regardless of their genetic or physical departure from the norm, is nevertheless either one or the other, male or female.
But I can foresee that there could be an anomalous situation where it really can’t be said “which one they are” — either “about half one and about half the other” (not only physiology or even chromosomes, but psychological makeup and “what they feel like they are” along with those factors, and possibly more important than those factors), or possibly “not really either one”. This would not vitiate the Church’s teaching, from Scripture, that “male and female He made them”, but rather, would acknowledge that, in some rare cases, there are people who don’t fit into either category to the exclusion of the other, nor even “some characteristics of one, but basically the other”. I’m afraid that the Church is trying to “shoehorn” the reality of these rare situations into a dichotomy that might not hold true for each and every member of the human race. I’m not at all clear, that it is an immutable doctrine of the Catholic Faith, that
there is no such thing as a totally intersex person whose sexual identity is irresolvable. The exact nature of the Ethiopian’s “eunuchness” isn’t discussed in Acts chapter 8, though male pronouns are used.
Though played for laughs (and it would not be possible to do this in today’s world), the “Pat” character from
Saturday Night Live is a perfect example of what I’m talking about. Thankfully, the question of “what, exactly, does Pat
have?” never came up, and was never resolved.
