NEW YORK

A campaign by outraged Roman Catholics to keep President Barack Obama from delivering the commencement address at Notre Dame shows that the gulf between the church and backers of abortion rights remains deep.

Yet the effort to get the school to rescind its invitation to Obama also highlights a political disconnect between the conservative Catholic hierarchy and millions of U.S. Catholic voters.

Since the White House announced in March that Obama had accepted Notre Dame’s invitation to speak May 17, more than 358,000 people have signed an online petition demanding that the university take back the offer. The Cardinal Newman Society, an advocacy group for Catholic colleges that circulated the position, said the invitation violated a 2004 bishops’ mandate that stated, “The Catholic community and Catholic institutions should not honor those who act in defiance of our fundamental moral principles.”

One Catholic leader, Archbishop Raymond Burke, accused Obama of pushing an anti-life, anti-family agenda. Burke, the first American to lead the Vatican supreme court, said Friday it was “a scandal” that Notre Dame had invited Obama to speak.

Catholic activists and bishops have been outspoken in their criticism of Obama. By comparison, they had only occasional disagreements with President George W. Bush, primarily over the U.S. invasion of Iraq, which the Vatican condemned but many conservative Catholics supported.

They cite his support for abortion rights and embryonic stem cell research, and his repeal of a policy that denied federal dollars to international relief organizations that provide abortions or abortion-related information. They remain angry with Obama’s support for legislation that would prohibit state and local governments from interfering with a woman’s right to obtain an abortion.

Obama also has been criticized by Catholics and other opponents of legal abortion for telling Pastor Rick Warren at a campaign forum last summer that the question of when life begins was “above my pay grade.”
