One way in which they were different was in that one was practical, while the other was not.
One way in which they were very much alike was attentiveness.
Martha was attentive to Christ in the practical details of hospitality.
Mary was attentive to Christ in the words he spoke.
May you and I be always attentive to Christ both in the practical details of our lives and also in our prayerful reflection on his word.
On this day the Church celebrates the memory of Saint Martha.
