Bede the Venerable — as excerpted in the Catena Aurea on Luke 9:51-56

“For holy men who well knew that that death which detaches the soul from the body was not to be feared, still because of their feelings who feared it, punished some sins with death, that both the living might be struck with a wholesome dread, and those who were punished with death might receive harm not from death itself but from sin, which would be increased were they to live.”
