Timothy Dolan, the archbishop of New York, says politicians 'deceived' Catholic bishops on a gay marriage bill.

While Dolan vigorously objected to passage of the bill, critics noted that few other bishops spoke out on the issue and Dolan himself wasn't in New York the day lawmakers approved the law in June.

Writing at the blog Queering the Church, gay rights activist Terence Weldon described the response of the bishops as “muted and moderate.”

Dolan told Global Catholic Television Network's (EWTN) Raymond Arroyo during a video interview conducted in August that lawmakers had assured the bishops that the bill would fail.

“We fell for the assurances of people that we thought were political allies that this wasn't going to go anywhere,” Dolan said.

“So we had political allies who said, 'Bishops, keep your ammo dry, you don't have to pull out all the stops, speak on principle, speak up against this bill, but don't really worry because it's not going to go anywhere.”

“We were told that Raymond, up to six days before the bill passed.”

“It sort of taught us that it's not all that good to trust politicians sometimes,” he added. “And I think some of us bishops think we were being deceived. And I think that could be, shame on us for believing them,” Dolan added. (The video is embedded in the right panel of this page. Visit our video library for more videos.)

Earlier this month, the United States Conference of Catholic Bishops (USCCB) launched a campaign described as an effort to “promote and defend marriage as the union between one man and one woman.”

Dolan is also the president of the USCCB.
