well I do disagree with your history and literal flesh/blood but that is not on topic. How hard it is for man to be saved in fact impossible, but with god all things are possible.
John 14: 6-7 Jesus said to him, ‘I am the way, and the truth, and the life. No one comes to the Father except through me. If you know me, you will know my Father also. From now on you do know Him and have seen Him.’
Jesus is the truth. Jesus is true God and true man.
I would say add
john 3.16
John 3: 16 For God so loved the world that He gave His only Son, so that everyone who believes in Him may not perish but may have eternal life.
The quote that you believe in. But Jesus qualifies everything that He says to us. If you read further into the Gospel of John… you’ll reach
–John 6: 35-36 Jesus said to them, ‘I am the bread of life. Whoever comes to Me will never be hungry, and whoever believes in Me will never be thirsty. But I said to you that you have seen Me and yet you do not believe.’
and
–John 6: 51 Very truly, I tell you, whoever believes has eternal life. I am the bread of life. Your ancestors ate the manna in the wilderness, and they died. This is the bread that comes down from heaven, so that one may eat of it and not die. I am the living bread that comes down from heaven. Whoever eats of this bread will live for ever; and the bread that I will give for the life of the world is My flesh.
and then
–John 6: 53-58 Very truly, I tell you, unless you eat the flesh of the Son of man and drink His blood, you have no life in you. Those who eat My flesh and drink My blood have eternal life, and I will raise him up on the last day; for My flesh is true food and My blood is true drink. Those who eat My flesh and drink My blood abide in me, and I in them. Just as the living Father sent Me, and I live because of the Father, so whoever eats Me will live because of Me. This is the bread that came down from heaven, not like that which your ancestors ate, and they died. But the one who eats this bread will live for ever.’
Now we come to the Lord’s Supper.
Matthew 26: 26-28 While they were eating, Jesus took a loaf of bread, and after blessing it He broke it, gave it to the disciples, and said, ‘Take, eat; this is My body.’ Then He took a cup, and after giving thanks He gave it to them, saying, ‘Drink from it, all of you; for this is My blood of the covenant, which is poured out for many for the forgiveness of sins…’
You have built your life around the one comment about salvation. Do you not see the error of taking only one truth that Jesus has said, without taking everything that Jesus has said, as truth?
Btw, I was thinking about this whole thread yesterday. It seems that Protestants misunderstand Catholics about works, while Catholics misunderstand Protestants about Faith… but the truth is that Catholics don’t look at works as ‘earning’ salvation… we don’t reckon them up to determine whether we’ve gained enough points to enter heaven… what we really do is hope for heaven… we know that we are sinners and aren’t worthy of heaven but we try to do our best to follow Christ in all His teachings and hope for salvation.
