Released. There was quite a brouhaha when this came out. First that there was a request for clarification at all, then because a letter was sent to Pope Francis requesting an audience.
Truth be told, I typically stay out of the inside baseball stuff of Church polity. Every tradition has its Robert’s Rules, and I am not an expert to praise or condemn what the Cardinals did, or how they did it.
Nonetheless, the letter in the article doesn’t appear haughty or disrespectful in the least. It appears to be quite humble, respectful and it merely acknowledges a fact: that Amoris Laetitia has created confusion among some believers. Even if there shouldn’t be a reason to have a problem understanding its teachings, the fact is they do. And they are still children of God, and fellow believers within the Faith. They deserve clarity.
