The church has changed all of this and added. All false teachings.The beast changes the moral laws, acceptance of homosexuality etc. as we are seeing today. The Sabbath is always the sabbath,a day of rest. That's why Sunday, the Lord's day was never called "The Sabbath" by the early Christians. Sunday, the Lord's day is foreshadowed through the "eighth day" mentioned in Leviticus. The first two feasts, Passover and first fruits have been fulfilled by Jesus through His death and resurrection. Tabernacles represents His second coming when He returns in Zechariah 14 where the feast is celebrated. Jesus' death and resurrection are observed as He instigated the New Covenant.
