Well, female deacons, from the little that we know and can prove, performed the function of assisting at baptisms of women (and baptism, by full immersion, was done in the nude so having men to administer would be a problem!)
They were not ordained. Ever.
So since we rarely have full immersion baptisms in the nude, since we already have plenty of lay women (i.e., not ordained) who can have all kinds of titles, and do, like director of religious education, parish coordinator, etc. etc., and since the term ‘female deacon’ would confuse the Hades out of most people because they would equate it with the (ordained) office of deacon, I think that Pope Francis will, as previous Popes before him have done, study the question and come to the conclusion that there is no area where a non-ordained woman performing the functions that non-ordained women already do needs to have a confusing title placed upon her in order to satisfy a certain contingent of nagging people who want an ego-boo. . .that is my opinion, of course, with absolutely no intent to deride or disparage anyone who thinks differently, and I am as always open to people with different ideas.
