Burch, the head of the pro-life organization Fidelis, tells LifeNews.com that Biden's pro-abortion views, like Obama's, pose a major challenge for American Catholics.
Fidelis warned late last month that a pro-abortion Catholic choice as a vice presidential candidate would offend many Catholics who have struggled with the scandal of prominent pro-abortion Catholic politicians like Senator Biden.
Barack Obama has re-opened a wound among American Catholics by picking a pro-abortion Catholic politician," Burch said.
"The American bishops have made clear that Catholic political leaders must defend the dignity of every human person, including the unborn. Sadly, Joe Bidens tenure in the United States Senate has been marked by steadfast support for legal abortion," he added.
Burch pointed to history to support his contention.
In 2004, John Kerrys support for abortion sparked a nationwide controversy over whether Catholics who support legal abortion can receive communion. The debate was re-activated in 2007 when several bishops criticized Rudy Giuliani, also a pro-abortion Catholic.
Now everywhere Biden campaigns, we'll have this question of whether a pro-abortion Catholic can receive communion," he told LifeNews.com.
"Senator Biden is an unrepentant supporter of abortion in direct opposition to the Church he claims as his own. Selecting a pro-abortion Catholic is a slap in the face to Catholic voters, he said.
Biden's own bishop, Bishop Michael Saltarelli of Wilmington, Delaware, has said that the issues pertaining to the sanctity of human life are the "great civil rights issues of this generation.
Bishop Saltarelli denounced the notion that politicians like Biden can 'personally oppose' abortion, but refuse to pass laws protecting the unborn.
"No one today would accept this statement from any public servant: 'I am personally opposed to human slavery and racism but will not impose my personal conviction in the legislative arena.' Likewise, none of us should accept this statement from any public servant: 'I am personally opposed to abortion but will not impose my personal conviction in the legislative arena,' said Bishop Saltarelli.
In fact, Bishop Saltarelli made clear that pro-abortion Catholic politicians should refrain from receiving the Eucharist.
"The promotion of abortion by any Catholic is a grave and serious matter. Objectively, according to the constant teaching of the Scriptures and the Church, it would be more spiritually beneficial for such a person to refrain from receiving the Body and Blood of Christ. I ask Catholics in this position to have the integrity to respect the Eucharist, Catholic teaching and the Catholic faithful," he said.
"Burch concluded: The American bishops have instructed Catholic voters to consider many issues, but have characterized the defense of human life as foundational and have explained that the issue has a special claim on the conscience of the Catholic voter."
"This means that a political candidate like Biden, because of his strong support for abortion rights, forfeits any claim for support despite his views on other issues like health care and the economy.
