We read of the miraculous cure of the man born blind , and the words of the Lord preceding the incident , at John 9: 4-5:
"We must work the works of him who sent me while it is day; night is coming when no one can work. As long as I am in the world, I am the light of the world.”
Jesus is not, in any way, referring to the earthly phenomenon of night. Is he alluring to his own death, or the persecution of the Church that was forthcoming ? My question therefore is: According to Catholic Church, what did Jesus mean by saying "night is coming.." at Jn 9: 4 ?
