QUESTION 04: Why celebtate the Feasts of the L-RD?
It is obvious from your question that the Biblical word ‘fulfilled’ means finished and so ‘done away with’ to you. Let us apply that same logic to the fulfillment of Passover by Messiah Jesus THE Lamb of GOD. Since Messiah Jesus ‘fulfilled’ forgiveness of sin on the Cross, salvation is fulfilled (finished). Thus no one since that generation is to be saved. Once a prophecy is ‘fulfilled’ it is completed and will not be repeated. So, following that logic we should not celebrate communion, the last Passover supper any more either.
However, we know that the LORD instructed His disciples to continue to celebrate the Last Passover Supper in memory of Him until He returns.1 Corinthians 11:26
“For as often as ye eat this bread, and drink this cup, ye do show the Lord’s death till He come.” (KJV)
There are seven Feasts of the LORD; Messiah has fulfilled the first four and will fulfill the last three. The seventh Feast is Tabernacles. It will be ‘fulfilled’ when the LORD comes to rule in the Millennium. Even though His return to earth is the ‘fulfillment’ of Tabernacles it is certainly NOT ‘done away with.’ Here is what happens following Armageddon.
Zechariah 14:16
“And it shall come to pass, that every one that is left of all the nations which came against Jerusalem shall even go up from year to year to worship the King, the LORD of hosts, and to keep the Feast of Tabernacles.” (KJV)
The oft-repeated phrase ‘the church was born on the Day of Pentecost’ is a theological error. The church was ‘born’ on resurrection day, Mary Magdalene being the first member to believe in the resurrection and acknowledge Jesus as LORD. Messiah told His followers to stay in Jerusalem until they ‘received power.’ (Acts 1:8). The 120 were already ‘born again.’
