In a 60-second video released on Friday, Fr. James Altman exhorts Catholics to "ponder what it means to be faithful."
Faithful Catholics, he notes, do not:
Biden, as the La Crosse cleric points out, has done each of these.
"The only responsible response to that would be to pass legislation making Roe the law of the land. That's what I would do," Biden pledged on Monday.
In August 2016, the vice president officiated a same-sex "wedding" at his private residence in Washington.
"Proud to marry Brian and Joe at my house," he tweeted. "Couldn't be happier, two longtime White House staffers, two great guys."
"I will restore the Obama-Biden policy that existed before the [2014 Supreme Court] Hobby Lobby ruling," he said.
Nearly five months after leftist riots erupted across the United States, Biden has yet to condemn the attacks on Catholic churches, statues and shrines that accompanied violence by Black Lives Matter and Antifa.
Buttressing his assessment of the former vice president, Fr. Altman notes in his video that Cdl. Raymond Burke "has correctly stated that Joe Biden is not a faithful Catholic."
"Certainly he is not a Catholic in good standing, and he should not approach to receive Holy Communion," Burke said of Biden during an interview in September. "A Catholic may not support abortion in any shape or form because it is one of the most grievous sins against human life. It is always been considered to be intrinsically evil, and to in any way support the act is a mortal sin."
Father Altman closes his video by exhorting Catholics to think and act according to the moral precepts of the Church.
"Don't be deceived by wolves in sheep's clothing," he cautioned. "Form your conscience in truth. Act like a faithful Catholic and vote this November."
