Christ Ahnsahnghong has preached the Passover of the new covenant when He was on the earth. Because the Passover of the new covenant was abolished A.D. 325 by Satan. So nobody had not kept the Passover. But the Passover is the truth that lead us to eternal life. Because Jesus said that we would have eternal life if we ate His flesh and drank His blood. And we can eat His flesh and drink His blood through the Passover of the new covenant.

While they were eating, Jesus took bread, and when he had given thanks, he broke it and gave it to his disciples, saying, "Take and eat; this is my body." Then he took a cup, and when he had given thanks, he gave 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."(Mt 26:26-28)
