Vatican News has a straightforward news report on the CDF's intervention with the USCCB and that Conference coming up with a national policy about worthiness to receive Holy Communion of President Biden.
Your can read the entire article HERE.
I would like to make some comments of the last part of the article. My comments in red.
[Cardinal Ladaria] stressed that “If it then decided to formulate a national policy on worthiness for communion, such a statement would need to express a true consensus of the bishops on the matter, while observing the prerequisite that any provisions of the Conference in this area would respect the rights of individual Ordinaries in their dioceses and the prerogatives of the Holy See.”
The above paragraph is very traditional and sounds like Cardinal Ratzinger/Pope Benedict and his emphasis on individual bishops in relationship to the pope rather than a collective of bishops centralized in a Conference of Bishops. The individual bishop is the "pope" of his diocese and has all at his disposal in terms of Canon Law and what is require of him in terms of his vow of obedience to the Pope and his relationship to the worldwide college of bishops. In other words, it seems Cardinal Ladaria is on the same page as Pope Benedict in this regard.
He added that “any statement of the conference regarding Catholic political leaders would best be framed within the broad context of worthiness for the reception of Holy Communion on the part of all the faithful, rather than only one category of Catholics, reflecting their obligation to conform their lives to the entire Gospel of Jesus Christ as they prepare to receive the sacrament.”
Yes, thank you Cardinal Ladaria. You hit the nail on the head. Each Sunday scores of Catholics present themselves for Holy Communion. Those in illicit unions that mock the Sacrament of Holy Matrimony, regularly receive Holy Communion when they attend Mass, although infrequently and without the benefit of Sacramental Confession or even a "perfect Act of Contrition." Each bishop and his priests have a grave responsibility to teach who should present themselves for Holy Communion.
In the case of public sin, meaning it is known that such and such is a mafia leader, loan shark, rips off the poor, works in an abortion clinic, is illicitly living with someone in a mock marriage, the pastor needs to speak to such person and remind them not to receive Holy Communion until they are reconciled to the Church. Most of the time, though, it pertains to parishioners in illicit marital like unions.
Public persons, such as politicians and those in high government positions, need to be told by their bishop after dialogue.
Furthermore, he pointed out that ““it would be misleading if such a statement were to give the impression that abortion and euthanasia alone constitute the only grave matters of Catholic moral and social teaching that demand the fullest level of accountability on the part of Catholics.”
Thank you Cardinal Ladaria, yes, there are other areas that should be called out and not just pro-abortion politics. And that applies to public and private persons.
Cardinal Ladaria, therefore, urged that “every effort” be made to dialogue with other episcopal conferences so as to “preserve unity” in the universal Church.
The good cardinal has said the same thing about the divisive synodal path Germany is on and their desire to negate the foundation of the moral teachings of the Church which are: Scripture and Tradition; the Deposit of Faith; the perennial Magisterium of the Church;natural law; their union with the pope and the college of bishops in union with the pope.
