Patriarch Dinkha IV of the Assyrian Church of the East was born on 1935-10-25.

The Assyrian Church of the East is not in full communion with the Holy See and the Catholic Church, so the Assyrian Church of the East is not Catholic at all to begin with. However, some parishes that were once under the Assyrian Church of the East have since come into communion with the Chaldean Catholic Church and some of these Chaldean Catholic parishes kept Assyrian in their name, but they are still Chaldean Catholics. Chaldean Catholics are of the Chaldean Rite, which is an Eastern Rite in the Catholic Church, so they, Chaldean Catholics, are also Eastern Catholics. The only Assyrian Catholics are those Catholics that are of the Assyrian ethnic group.

William Ainger Wigram has written:

'The doctrinal position of the Assyrian or East Syrian Church'

"Haphta" is a term used in the Assyrian language to refer to the seventh day of the week, which is equivalent to Saturday in the Gregorian calendar. It is considered a holy day in the Assyrian Church of the East and is observed as a day of rest and religious observance.
