Updated at 11:05 p.m. ET: Bishop Salvatore Cordileone, San Francisco's Roman Catholic archbishop-elect who was arrested early Monday for driving under the influence in San Diego, apologized, saying he felt "shame for the disgrace I have brought upon the church and myself."

Cordileone, who last month was named the next archbishop of San Francisco, was arrested early Saturday morning, according to police. Authorities stopped him at a checkpoint near the San Diego State University campus, the AP reported.

Cordileone, a San Diego native, was released on $2,500 bail about 11 hours after his release, a San Diego detective told Reuters. He had been booked on a misdemeanor DUI charge after he was stopped at a police checkpoint and failed a field sobriety test.

In his apology, released as a statement by his diocese, Cordileone said: "I will repay my debt to society, and I ask forgiveness from my family and my friends and co-workers at the Diocese of Oakland and the Archdiocese of San Francisco. I pray that God, in His inscrutable wisdom, will bring some good out of this."

Cordileone, 56, is currently the bishop in the Diocese of Oakland, Calif. Previously, Cordileone was an auxiliary bishop in San Diego, the AP reported.

He is expected to take over San Francisco's top spot when the current archbishop, 76-year-old George H. Niederauer, retires in October. Cordileone must make a court appearance on Oct. 9, the AP reported.

Michael Ritty, a private practice canon lawyer in upstate New York, told the AP that since Catholic bishops are accountable to the pope, potential discipline would have to come from the Vatican.

"If there was anything, it would be handled in Rome, most likely by the Congregation for Bishops. Depending on the question or type of criminal charge, it might go directly to the Pope or as directly as you can get," Ritty said.

Cordileone is known for being a strong, public opponent of same-sex marriage, and he is expected to govern 432,000 Catholics under his new post in the largely gay-friendly Bay Area. He'll also oversee the bishops in Honolulu, Las Vegas, Oakland, Reno, Sacramento, Salt Lake City, San Jose, Santa Rosa and Stockton, according to the AP.

The Archdiocese of San Francisco office declined to comment.

In a city with one of the largest gay communities, the Vatican on Friday named San Francisco's newest archbishop: a man who is a strong opponent of same-sex marriage.

The central governing body of the Roman Catholic Church picked Bishop Salvatore Cordileone, who is currently the bishop in the Diocese of Oakland, Calif. Cordileone, who will soon govern more than 432,000 Catholics in San Francisco under his new title, has publicly backed bans for same-sex marriage.

Cordileone, 56, supported California's controversial Proposition 8, the San Francisco Chronicle reported. During the state's November 2008 election, Proposition 8 barely passed with a 52 percent vote and contradicted the California Supreme Court's ruling that had legalized same-sex marriage just five months before.

When interviewed by the Catholic Radio Network around that time, Cordileone characterized same-sex marriage as a plot by "the evil one" to destroy morality in the modern world, according to the Chronicle.

Friday's appointment comes after the resignation of San Francisco's current Archdiocese, 76-year-old George H. Niederauer, who held the position since late 2005.

"I look forward to assuming my new pastoral responsibilities with and for the priests and people of the Archdiocese of San Francisco," Cordileone said in a press conference statement.

"This isn't a marriage made in heaven," Tom Ammiano, a gay state assemblyman who represents San Francisco, told the Chronicle. Ammiano did say he's willing to discuss gay marriage with Cordileone.

In February, a federal appeals court found Prop 8 unconstitutional, but the U.S. Supreme Court will probably have the final say in its constitutionality.
