Mar Mari Emmanuel is an Iraqi-born, Assyrian Australian prelate. He is the bishop of Christ the Good Shepherd Church in Wakeley, New South Wales, which hosts the highest number of Assyrian Christians—many of them refugees from Iraq and Syria—in any suburban Australian neighbourhood.

On 15 April 2024, at approximately 7:15 pm local time, a knife attack took place at Christ The Good Shepherd Church in Wakeley, a suburb of Sydney, Australia. During a live-streamed sermon, the attacker walked up to the pulpit, first stabbing bishop Mari Emmanuel, resulting in permanent vision loss in Emmanuel's right eye, before stabbing a priest and injuring another churchgoer. While no one was killed, this attack was the second stabbing incident to have taken place in Sydney in three days, following the deadly mass stabbing at Bondi Junction.
