Here is a real prince of the Church. God bless him. The following interview on current events in the Church with George Weigel is also excellent.
You may also want to read “The German Church Divided” in the Catholic Thing. This regards communion for divorced and civilly remarried and communion for Protestants.
Also Fr. Dwight Longenecker’s article “Francis and Marx: Another Fine Mess” here. Should Protestants receive communion? If they want communion they should join full communion with the Catholic Church.
