In Luke 22, It doesn’t say Jesus ate lamb at Passover. Instead, he was the last supper of bread and wine… the feast of unleavened bread was the original celebration and typology of the Melchizedek offering. Jesus rejects the Passover lamb in the original Hebrew version of the gospel of Matthew, preserved by Epiphanius in his critique against the followers of James the Just (Jesus’ brother) who still used this text. This is because the Passover lamb is as never a part of the original faith.
