    \begin{itemize}

        \item There are obviously too many women of faith to
            consider any of them individually as the typical
            representative of all of them

        \item Moreover, most of them, given the ever-present
            misogyny of the time, are hidden behind the much more
            famous men

        \item And even those who famous on their own, like Hildegard of Bingen,
            Catherine of Sienna, or our own Saint Agnes of
            Bohemia, were daughters of kings or local nobleman,
            who are hard to follow by us mere mortals.

    \begin{quote}
    Meanwhile the disciples were urging him, “Rabbi, eat
    something.” But he said to them, “I have food to eat that
    you know nothing about.” So the disciples began to say to
    one another, “No one brought him anything to eat, did
    they?” Jesus said to them, “My food is to do the will of
    the one who sent me and to complete his work.
