A bishop and several worshippers have been attacked in another stabbing rampage to rock Sydney.

Bishop Mari Emmanuel was preaching at Christ The Good Shepherd Church in Wakeley in Sydney’s west on Monday just after 7pm when a man dressed in black walked up to the altar and allegedly stabbed him multiple times.

Horrifying footage of the incident, which was being broadcast live on the church’s YouTube page, shows Bishop Emmanuel look up in astonishment as the attacker suddenly rains down blows on his face and head.

Horrified screams can be heard as other worshippers rush to the bishop’s aid as he falls to the floor. 

Early reports suggest at least two others were also allegedly stabbed in the ensuing tussle. 

It comes just 48 hours after six people were murdered in Westfield Bondi Junction by a crazed knifeman.

Joel Cauchi, 40, stabbed five women and a male security guard to death and injured several others before he was gunned down by a police officer. 

Daily Mail Australia has approached NSW Police for comment.

Christ The Good Shepherd Church has almost 200,000 subscribers on YouTube. 

More to come.
