Thanks for the link. But I find that line of reasoning bizarre. I’ve read a couple of Kreeft’s books, BTW, and generally like the way he writes but I’m not impressed by his logic on quite a few occasions – but I understand here he’s simply repeating the RC line. By his logic, all use of feminine imagery to describe God should be false and heretical. Yet Jesus himself used such imagery (e.g. Mt 23:37). Genesis shows the division between male and female as coming before the fall, and indeed acknowledges that God created them “in his own image, male and female.” There is absolutely nothing less godly about females than there is about males. And Paul does not say males and females can both be members of the Church; he says in Christ there is no such valid distinction.
In addition, there are many instances in the early Church of women being ordained, although it was always a localized and evidently somewhat eccentric process (c.f. Madigan and Osiek, “Ordained Women in the Early Church”). Imagining that local and eccentric processes are always heretical is to retroject a level of papal uniformity back into an ecclesial system that knew no such discipline.
Very complex and detailed, scripture-filled justifications have been written for centuries justifying mandatory priestly celibacy – and yet the Catholic Church turns right around and allows married priests in Uniate and ex-Anglican jurisdictions. Obviously not every issue of human sexuality rises to the same level.
Admittedely, when I first started looking at Christianity, I attended a local Episcopalian church for a few weeks. For various reasons, I switched to going to Catholic Mass, and studying Catholic teaching. I was reading “Catholic for Dummies” in a Barnes and Noble, and turned to the section on the male-only priesthood. The “reasoning” in that particular book really ticked me off. I literally threw the book down. But I didn’t stop reading there, and looked for what other’s had to say.
Coming from an atheist/nihilist/feminist view, at the time, you can believe that any old explanation wasn’t going to fly. Some things in your post here, that just are not the Catholic view. No one believes there is anything “less godly about females”. Honestly, that sounds like a Mormon left-over. No one believes that sexuality defines our spirituality. If anything, now, I read such ideas as saying that my sexuality
should define my spirituality, so therefore I should be upset that the Catholic Church doesn’t acknowledge this definition. I don’t acknowledge it.
God became Man and dwelt among us. God didn’t become Woman. Should I be upset at this? Should I think God thinks anything less of me because God became Man? If so, why?
In the context of the Sacrifice at Mass, Jesus Christ fulfilling the office of the High Priest (always male), I can’t see a reason that makes sense that a priest would be female. Sure, in my nihilist pre-convert days, I’d say all of this was a social construct, which is what you are saying. But you have to understand, a nihilist sees
everything as a construct. So when you are someone who believes there is
nothing, wondering if there is
something, and that
something turns out to be a Person…well, who am I to say that Jesus taking on the vesture of a human male, and our continued Sacred Tradition to honor the Person of Jesus Christ in every way, is a human construct? For me, I believe in the REALITY of Jesus Christ. In the REALITY of the Church He established. If you want to start breaking down social constructs, a nihilist can tear down your belief to block on block of human constructs. If this is your orientation towards reality, I can make you an atheist in a week! I’d rather point you to the Reality of Jesus Christ, the event of the Incarnation, where God became Man. An Event that changed humanity. Your Salvation.
And all that being said.

All the baptized share in the priesthood of our one High Priest, Jesus Christ. All of us, clergy and laity, male and female, are a chosen people, a royal priesthood, a holy nation.
God bless you.
