"My friends, it takes no humility on my part to admit that I am not the light," Brennan said, provoking laughter from the congregation. Instead, he said, it is the light of Christ that will lead the diocese out of these "dark times" and into a future of hope.
"The light of Christ beckons us to move now from the painful past toward him, not in denial but in confidence that the Lord will supply us with the wisdom and strength to do things better, to live our faith with greater integrity and to reflect more brightly, as far as our human weakness and limitations will permit, his own enduring light," he said.
Brennan acknowledged numerous groups of people whom he said have already been lights in the darkness, including parents who continue to catechize their children, Catholic school and religious education teachers who do the same, parish priests who faithfully administer the sacraments, as well as diocesan chancery workers and faithful young people.
"Christ's light has been shining in the darkness through all of them and, as St. John says in his Gospel, the darkness has not overcome it. I thank God for these faithful West Virginia Catholics," he said.
The scandals may also have driven some people away from the Church, Brennan said, but he encouraged Catholics in the diocese to look to their roots circa the Civil War - when West Virginia seceded from Virginia in order to remain in the Union - for inspiration to remain united in faith.
"When the dark clouds of secession were rolling over the State of Virginia in the spring of 1861, the people of these western mountains chose to remain in the United States of America. They would not break their unity with Ohio and Pennsylvania, Michigan and Kentucky. They petitioned Congress to admit them as the State of West Virginia, which Congress did in 1863," he said.
"Many of their sons-the ancestors of some here present - fought to maintain the integrity of the Union."
He urged Catholics of today to fight for that same unity in the Church.
"Unity with one another and with God is what the Lord wants for us- and what, in our hearts, we truly desire," he said.
"One man told me not long ago that he stopped going to Mass in his parish because of the recent scandals but then he asked himself: who was he helping by doing that? No one. Who was he hurting? Himself. He has since returned to Mass, still eager to see the Church address its failings and bring about lasting reform but conscious that walking away doesn't help," he added.
"As Simon Peter said to the Lord when some disciples were leaving Jesus because of hard teachings, 'Lord to whom shall we go? You alone have the words of eternal life.'" The Blessed Virgin Mary is another example of someone who said "yes" to the Lord despite difficult circumstances, Brennan said.

"...like Mary, we can let God fulfill his purpose in us and not let the darkness return to cover the earth. We can right the wrongs of the past and move on to make Christ known, helping our neighbor in need and remaining united in faith and love," he said.
"West Virginia Catholics: cherish your faith and the holy Church that has nurtured it," he added.
"Make Mary's 'yes' to God your own and work with me and your brothers and sisters to let the light of Christ be a light brightly visible in the mountains and valleys, the city streets and country roads of this beautiful part of God's creation: West Virginia."
