An evangelical priest was attacked by a knifeman during a church service in Brazil that was being streamed on Facebook Live.
The 26-year-old suspect as the reading was broadcast on social media because he did not like the sermon, according to reports.
He was filmed walking calmly up stairs to the right of the pulpit before pulling out the weapon he was carrying inside the top of his trousers.
Church-goers could be overheard screaming warnings to the clergyman, who held up his microphone to defend himself.
A brave worshipper rushed up behind the attacker and got him in a bear hug as he slashed at his victim with the knife.
