Pope Benedict XVI said, “The heart open to God, purified by contemplation of God, is stronger than guns and weapons of every kind … the Evil One has power in this world, as we experience continually; he has power because our freedom continually lets itself be led away from God.”
This brings us to the key to Pope John Paul II’s master plan for the new millennium, as he asks us to set aside our disconnected busy-ness, and to start fresh by contemplating the face of Christ. It is clear that the Holy Father was encouraging us to place our emphasis on reconnecting to the Divine Life of God, which is classically referred to as the unum necessarium, the one thing necessary.
The “one thing necessary” constitutes the essential foundation for the interior life and consists in hearing the word of God and living by it (I will serve!). It stems from the story of Martha and Mary (Lk 10:38-42), where we first see that, amazingly, the Second Person of the Holy Trinity was sitting right in their living room. Now, Martha remains busy with the good and noble protocol of hospitality while Mary sits at the feet of Jesus, her eyes locked on his holy face, peering into his soul, hanging on his every word. Mary is actually in adoration, soaking in everything our Lord wants to give her. I like to say that she is “Mary-nating” – soaking in the gusher of God’s graces.
When Martha objects to Mary’s lack of activity, Jesus tells Martha that she remains anxious and upset about many things while Mary has chosen the better portion, the “one thing necessary” (unum necessarium). Mary was the one who was making the guest truly feel welcomed while Martha remained detached, going through the motions of the demands of protocol. God is light and love and truth who brings order and meaning and serenity to our lives. While we remain disconnected from our Source, we remain easily agitated and frustrated in our disordered and chaotic existence as we continue to walk in darkness.
