Croneberger was serving as rector at the Church of the Atonement in Tenafly, New Jersey, in June 1998 when he was elected as Bishop of Newark. He was consecrated as Bishop Coadjutor on November 21 of the same year.[1][2]
Croneberger succeeded Bishop John Shelby Spong on February 26, 2000, in an installation ceremony at Trinity & St. Philip's Cathedral, Newark.
As diocesan bishop, he continued Spong's agenda of radical inclusion. On accepting LGBTQ inclusion in the Episcopal Church, Croneberger said:[3]
"Supporting" inclusion "may be more important than unity within the worldwide Anglican communion."
On April 6, 2005, he announced his intention to retire in January 2007, citing the health of his wife, Marilyn.[4]
The diocese held a special convention to elect his successor on September 23, 2006. Mark Beckwith, the rector of All Saints' Episcopal Church in Worcester, Massachusetts, was elected on the third ballot.[5]
