That diocese’s vicar general in his statement also noted, “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. 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. Eternal rest be granted unto Bishop Dorsonville and may God’s perpetual light be upon him. Amen.”
