Fainu, 24, pleaded not guilty to plunging a steak knife into the back of Faamanu Levi at the Church of Jesus Christ of Latter-day Saints at Wattle Grove in southwestern Sydney on the evening of October 25, 2019.
But it only took the jury a few hours to find him guilty of one count of wounding a person with intent to cause grievous bodily harm and is facing a maximum of 25 years in prison.
