A distinction without a difference. Where then are the Teachings of the Catholic Church? Where are the official positions of the Catholic church if not in the USCCB? (Keeping in mind that one of those quotes was from a pope, not the USCBB.
The Teachings of the Catholic Church are found in the unadultrated Bible and are explained in the Catechism.
Since the link is blown, please provide the quote from the Pope, and I’ll be happy to address it.
Although, I susspect AB Chaput has done that work already in “Render unto Caeser”.
Charity is not the job of the government.
If it's not an infallible teaching, Catholics of Good Will can disagree on it.
Official Catholic teaching comes through (a) the Pope, (b) the bishops teaching in union with him; and (c) [secondarily] the documents promulgated under the Pope's authority by the Vatican offices which report to him.
National bishop's conferences, like the USCCB, aren't authoritative teaching organs. They can express opinions of course, but those opinions aren't binding on anyone's conscience. The "chain of command" in the Church goes directly from an individual bishop to the Pope, not through the national bishop's conference.
National bishop's conferences have some authority, but it's primarily over administrative and liturgical issues (e.g., making sure that the Mass is said the same way throughout the US), not doctrinal ones.
