The Wisdom of Solomon “The Lord created me at the beginning of his work, The first of his acts of long ago. Ages ago I was set up, at the first, before the beginning of the Earth. When he established the heavens, I was there.” “The Lord created me at the beginning of his work, The first of his acts of long ago. Ages ago I was set up, at the first, before the beginning of the Earth. When he established the heavens, I was there.” Proverbs 8:22-23, 27 © Copyright, Dr. Aileen O’Donoghue, St. Lawrence University

“In the beginning when God Created the heavens and the Earth, the Earth was a formless void and darkness covered the face of the deep” “In the beginning when God Created the heavens and the Earth, the Earth was a formless void and darkness covered the face of the deep” Genesis 1:1 © Copyright, Dr. Aileen O’Donoghue, St. Lawrence University

Darkness As Something The Principle and Foundation of St. Ignatius All of God’s created cosmos is intended to reveal this sharing of God’s life and love. We are created to share in God’s love and life for eternity. The experience of this love is manifested in our response of praise, reverence and service, that is, loving God with all our heart all our mind and all our will. cf.

Beginning Retreat: Seek The Darkness Sit with darkness … What can you see there that you can’t see in the daylight? Know that the frozen energy of the Big Bang you’re sitting on allows the darkness to exist … Seek to comprehend that the darkness came into being through the Word and is not separate from God’s creative Love … Sit with darkness … What can you see there that you can’t see in the daylight?

In the beginning … there was the Word; The Word was in God’s presence, and the Word was God.
