Jesus speaking to Nicodemus, to introduce the Gospel of the Grace of God in Christ Jesus:
John 3:14 And as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, 15 that whoever believes in him may have eternal life.
Jesus speaking to a crowd of unbelievers seeking signs and more bread:
John 6:38 For I have come down from heaven, not to do my own will but the will of him who sent me. 39 And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day. 40 For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day.
Or is it libel, because it's written? I can't remember, I need more coffee.
But keep repeating that line about the Catholics. if it makes you feel better.
