From the article in the Herald:
"'Bishop Sullivan was a man of deep faith in God and commitment to the real presence of Jesus in the Eucharist,' his successor, Bishop Samuel J. Aquila, said in a statement. 'His devotion to the Blessed Virgin Mary, mother of Jesus Christ, inspired much of his work both inside and outside of the Diocese of Fargo,' Aquila said. 'He was a strong spiritual leader for the Catholic faithful and a loving father figure to the men who served as priests of the Diocese.'"
In addition, Bishop James Sullivan was a public pro-lifer. God rest his soul.
