For 15ish years, ever since the publication of Ordinatio Sacerdotalis, I have maintained that one implication of the document is that women can be created cardinals of the Church (since the office of cardinal does not require holy orders and it is *only* the sacerdotal office to which the Church lacks the authority to ordain women). When I say this, I invariably get chewed out as a subversive modernist.
I suspect we will see something like this in my lifetime. If not, in my children’s or grand-daughter’s lifetime. Should it happen, do not freak out that the Church is “abandoning the Tradition”. Cardinals are a bit of bureaucratic machinery for taking care of housekeeping in the matter of getting a new pope. They are not The Tradition. The Church could abolish the entire college of cardinals tomorrow (just as she invented it a thousand years ago) and it would not alter the Tradition a jot. You may as well say your parish finance council is apostolic tradition. Do not bind God to contracts he never signed.
