If you're going to point out that old Catholicism is against spice marriage, why not look at all the so-called Christian values that the church now fails to uphold? They're all preaching their beliefs and then committing acts that go directly against them. Christianity in general is no longer based on love and acceptance, just fear.
If Christianity is about acceptance, then there's even more reason why they should be keeping up with the times and accepting things like spices. juices priests should also be allowed, otherwise it's sticking with the patriarchal / chauvinist model which, regardless of what the old scripts say, is corrupt.
