A question to ponder.....Who benefits?
Because the Old Testament feasts,and physical ordinances had no bearing on spiritual salvation,but was only in place until Jesus came and gave spiritual salvation.
In the Old Testament there were the spiritual laws,moral laws,laws of love,but they could not receive the Spirit so they could not live up to those spiritual laws perfectly.
Jesus said a new commandment I give you,that you love one another as I have loved you,and love works no ill towards their neighbor,therefore love is the fulfilling of the law,and we establish the spiritual laws,moral laws,laws of love,which we can do because in the New Testament we can have the Spirit.
Love God,and love people,the 2 greatest commandments,and all the law and prophets hang on those two laws,and creation testifies that there is a God that loves people,so the world is without excuse,for that is what is all about from Adam in to eternity,love God,and love people.
Jesus took the physical ordinances of Israel out of the way,nailing them to His cross,for they were contrary to us,that they had no bearing on spiritual salvation,but was only in place until Jesus came,because in the Old Testament they could not receive the Spirit,so let no person judge you in those physical ordinances,for you do not have to keep them,and a person that receives the Spirit is part of the body of Christ,and physical ordinances have no place in their relationship with God.
Old Testament-could not have the Spirit,could not live up to the spiritual laws perfectly,so God had them do physical ordinances that they could keep,and to be right with Him.
That is why in the millennial reign of Christ,when Jesus and the saints will rule over the people that God spared when He went against the world,they have to go up year after year to Jerusalem to worship the LORD,and keep the Old Testament feast of tabernacles,for they cannot be spiritual,and be right with God,so they have to keep the feast of tabernacles to be right with Him.
In the Old Testament since they could not be spiritual,they had to do physical ordinaces to stay right with God.
New Testament-can have the Spirit,so they are spiritual,so physical ordinances do not apply to them,for there is no benefit to keeping the physical ordinances.
