I think the note from December 14 is, with respect to Non-Catholic Christians, is more accurately referring to restoring Unity among all Christians. Just a few days ago, the Karekin II, the Catholicos of the Armenian Church of the East, was in Rome discussing the path to restoring Full Communion with Rome. This is no small miracle when you realize that the Armenian Church split with Rome after the Council of Chalcedon in 451 AD. In 1996, the former Leader of the Armenian Church came to Rome and signed a document with Pope John Paul II ending the differences in Christological Doctrine from the Council, or the understanding of that Doctrine by the Armenian CHurch vs. Rome. What you are seeing is the Holy Spirit gradually bring about a restoration of Full Communion between the Catholic CHurch and The Bishop of Rome and the Armenian Eastern Church.

At the feast of Pentecost, which was Sunday May 11, the Pope also discussed Church Unity again. So, conversion of non-Catholics is not a technical theological term applied to Protestant-Christians who are received into Full Communion with the Catholic CHurhc as the Catholic Church dos “Not re-baptize” Protestant Christians who were baptized into a Protestant Confession using the Trinitarian formula, water, and having an orthodox view of the Trinity as expressed in the Creeds (Apostles and Nicene)
