The reason that the Johnson Amendment was passed in 1954 is because of people like Father Robert Morey of Saint Anthony Catholic Church in Florence, South Carolina, who refused to give communion to Joe Biden because of his stance on abortion. His action was purely a political stunt, which is why he invited the local press to attend the service.
Joe Biden is a devout Catholic, and was one of the sponsors of the 1974 Hyde amendment. He also is personally opposed to abortion, but he doesn't feel that he has the right to impose his beliefs on other people, which is what the evangelicals do all the time.
I did some research the other day about the Eucharist, and found that VERY FEW Catholics should be able to receive communion. Since at least 75% of the folks who call themselves Democrats feel that abortion should be allowed in at least some circumstances, there are MANY Catholic Democrats who Father Morey would deny communion to. Apart from their political affiliation, there are MANY other acts that should exclude Catholics from communion. The article at the link below goes into more detail:
The irony of the Johnson Amendment (which restricts political activities by church) is that it was passed the same year that we added "under God" to the pledge of allegiance. ("In God We Trust" became our official model 2 years later). In the early 21st century, many politicians, including President Donald Trump, have sought to repeal the provision, arguing that it restricts the free speech rights of churches and other religious groups. These efforts have been criticized because churches have fewer reporting requirements than other non-profit organizations, and because it would effectively make political contributions tax-deductible. On May 4, 2017, Trump signed an executive order "to defend the freedom of religion and speech" for the purpose of easing the Johnson Amendment's restrictions
Abortion has long been a controversial topic in this country. I published the article below more than 8 years ago - and 4 people someplace in the world read it yesterday.
What prompted me to write the article is a column by Nicholas Kristof of the New York Times who published the column below the day before:
The reason that about half (52%) of all U.S. adults who were raised Catholic have left the church at some point in their lives is due to the church's rigid stance on a number of topics, and Bishop Thomas Olmstead of Phoenix (mentioned in the article above) is a good example of the dogmatic leaders that still populate the church hierarchy.
Pope Francis is a breath of fresh air, but there are still plenty of Catholic leaders who feel that he is too liberal. His predecessor, a staunch conservative called Pope Benedict, actively suppressed sexual abuse cases when he was a Cardinal in Germany.
