Second Messiah? AhnSahngHong? Korean?

The bible testifies exactly how Christ gave us salvation 2000yrs ago.
John 6:53"Jesus said to them, "I tell you the truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day."
How do we eat Jesus Christ body and blood?
Matt.26:17-26"On the first day of the Feast of Unleavened Bread, the disciples came to Jesus and asked, "Where do you want us to make preparations for you to eat the Passover? He replied, "Go into the city to a certain man and tell him, 'The Teacher says: My appointed time is near. I am going to celebrate the Passover with my disciples at your house.'...While they were eating, Jesus took bread, gave thanks and broke it, and gave it to his disciples, saying, "Take and eat; this is my body." Then he took the cup, gave thanks and offered it to them, saying, "Drink from it, all of you. This is my blood of the covenant, which is poured out for many for the forgiveness of sins."
This was the way Christ gave us eternal life, salvation, 2000yrs ago, by celebrating the passover in which we can eat Jesus Christ body and blood. He never promised it on any other night. But when second coming Christ comes, he said he will bring salvation..... Then what must have happened to the Passover, the way to receive salvation?!!!! It was destroyed during the dark ages by Constantine the Great in 325AD during the Nicene Council! Then, when second Coming Christ coming to bring salvation, what must he reestablish? Passover. But who keeps passover nowadays? Why among all things to abolish, Satan who abolish the passover, the way to eternal life? The answer seems simple, but the real reason is so incredibly eye opening that wouldn't even believe it. keep reading to find out...until next time.
