(OSV News) -- Bishop Mario E. Dorsonville of Houma-Thibodaux, Louisiana, passed away unexpectedly late Jan 19 due to complications from recent health problems, according to a post from the diocese. He was 63.
Bishop Dorsonville had headed the diocese as its fifth bishop just under a year since his installation on March 29, 2023. Prior to that, the bishop had served as auxiliary bishop for the Archdiocese of Washington for eight years since his appointment in 2015.
"It is with great sadness and deep shock that I announce to you that our beloved Shepherd, Bishop Mario Dorsonville, passed away at 6:50 pm this evening after he gave in to complications arising from recent health problems," Father Simon Peter Engurait, the diocese's vicar general, said in posting the news of the bishop's death on social media Jan. 19.
"My heart is broken as I make this news to you as this is not the kind of message any one of us would expect to receive," he wrote. "I am aware that you will have a lot of questions on your mind. I ask that you be patient with us as we begin to navigate through these uncertain moments. In the meantime, I ask that you keep him in your prayers."
Bishop Michael G. Duca of Baton Rouge, Louisiana, said in a statement Jan. 19, "I was deeply saddened to hear of the untimely death of my brother bishop Mario Dorsonville of Houma-Thibodaux. The faithful of the Diocese of Baton Rouge join me in prayer for the people of his diocese who have embraced him so lovingly during his short time among them. May he rest eternally in the arms of our Lord and Savior."

It is your home and now it is mine too. I realize that a new chapter of my life has begun, knowing that the book gets better as the book goes on."
Promising that "from now on you are in my prayers," Bishop Dorsonville called on his new family of faith to "walk together to answer God's call to continue to build up the church we love ... if we do that together we will be closer to holiness."
