Jesus is the Lamb of God. Since Passover is a type and a foreshadowing we must as ourselves what did the Jews do with the sacrificed lamb? Had it live with them, killed it, and then ate it in order that the angel of death would Passover them. They did this in the manner of getting ready to travel to the promised land. As when we must do when we partake in Jesus teaching in John 6.
You said quite a bit to never answer my followup question. "How can he eat Jesus' flesh and drink His blood? Does He need to find Jesus, kill Him, and eat and drink?" Explain how this is to be done by the believer in Christ, so he may be saved. This is your belief system, you should be able to explain it.
The problem between your understanding of salvation and mine is that you need lists. I believe that once God has given you faith to believe in the Lord Jesus Christ your life is lived in Christ. In other words everything you do engages salvation. That is why I'm having a problem with lists. Do what Jesus says what he taught.
I need no list brother, I gave you my answer for salvation, you are the one who said it is "many things" in your Catholic answer to "what must i do to be saved?". I believe the problem you have is you do not understand the difference between salvation and the sanctifying work of the Spirit after one is saved (born-again) which is a one time event. You conflate the two and thus find yourself in the position of not being able to answer how a person is saved. In fact, you cannot even be sure of your own salvation, which is sad because that isn't the way God wants you to live. He wants you to know you are saved by grace, and this not of yourself, it is the gift of God. On the contrary, you believe salvation is of yourself, towing the line, making sure you do everything Jesus said to do or you might not make it. But you even know you do not do everything Jesus said to do, so what does that leave you with? It leaves you with the doctrine of Moroni, by Joseph Smith, which says "by grace ye are saved, after ye do all ye can do".
