Hi Liam,<quoted text>
The Vatican never said that. Whoever wrote the title of this forum added "Roman" in it. The Vatican said "Catholic Church". This statement doesn't only include the diocese of Rome. There are millions of eastern rite Catholics who are not Roman or Latin Catholic.
For example, the Malankarese Catholics who practice the Antiochean rite, hail from southern India and were founded by the Apostle Thomas, are a part of the true Church, but you couldn't call them "Roman Catholic" because they are not.
Thanks for the correction and explanation. I appreciate it :)
