From America Magazine, the Jesuit publication. With an explanation from the priest who refused communion to the pro-abortion politician.
The issue of Catholic politicians supporting abortion has been addressed at every level of the Catholic Church. In 2004, Cardinal Joseph Ratzinger, then prefect of the Congregation for the Doctrine of the Faith, wrote a memo on "Worthiness to Receive Holy Communion: General Principles."
In it he stated: "Regarding the grave sin of abortion or euthanasia, when a person's formal cooperation becomes manifest (understood, in the case of a Catholic politician, as his consistently campaigning and voting for permissive abortion and euthanasia laws), his pastor should meet with him, instructing him about the church's teaching, informing him that he is not to present himself for holy Communion until he brings to an end the objective situation of sin, and warning him that he will otherwise be denied the Eucharist."
"This decision, properly speaking, is not a sanction or a penalty. Nor is the minister of holy Communion passing judgment on the person's subjective guilt, but rather is reacting to the person's public unworthiness to receive holy Communion due to an objective situation of sin," Cardinal Ratzinger wrote.
In his statement, Father Morey offered his prayers for Biden.
"As a priest, it is my responsibility to minister to those souls entrusted to my care, and I must do so even in the most difficult situations," he stated.

Father Jay Scott Newman, pastor of St. Mary Church in Greenville, expressed support for Father Morey in an email to The Catholic Miscellany, newspaper of the Diocese of Charleston.
"As a canon lawyer, my own conviction is that Catholic politicians who support abortion do fall under the exclusion described by Canon 915 and that Father Morey arguably has the law on his side," he said. "Moreover, the law does not restrict to the diocesan bishop the decision to exclude from Communion someone who fits either category of Canon 915, so Father Morey did not exceed his authority."
"Perhaps the best analogy to this matter is the decision of several bishops during the struggle for civil rights to exclude from holy Communion those Catholic politicians who continued to oppose full integration for African Americans," Father Newman continued. "The archbishop of New Orleans, for example, was widely applauded for his courage in taking that step."
