Notice the three privileges given to Mary Magdalene. First, she had the privilege of being a prophet because she was worthy enough to see the angels, for a prophet is an intermediary between angels and the people. Secondly, she had the dignity or rank of an angel insofar as she looked upon Christ, on whom the angels desire to look. Thirdly, she has the office of an apostle; indeed she was an apostle to the apostles insofar as it was her task to announce our Lord's resurrection to the disciples. Thus, just as it was a woman who was the first to announce the words of death, so it was a woman who would be the first to announce the words of life.

The Latin, for those who are interested:
Ubi notandum est triplex privilegium, quod Magdalenae est collatum. Primo quidem propheticum, per hoc quod meruit Angelos videre: propheta enim est medius inter Angelos et populum. Secundo Angelorum fastigium, per hoc quod vidit Christum, in quem desiderant Angeli prospicere. Tertio officium apostolicum, immo facta est apostolorum apostola, per hoc quod ei committitur ut resurrectionem dominicam discipulis annuntiet: ut sicut mulier viro primo nuntiavit verba mortis, ita et mulier primo nuntiaret verba vitae.
