As Christians, we even as the first disciples hear the voice of Christ instructing us to go and make other disciples. When they believe, baptize them, and then teach them to observe all things that I have commanded you (Matthew 28:19-20). In instructing the Corinthian gentiles the apostle Paul taught them to keep the feast (1 Corinthians 5:6-8). But to do so in the marvelous light which was being, and is now revealed in and through the new priesthood of Christ (Hebrew 7:11-12).
For God has made known to His church that the substance of His Feast is Christ Jesus our Lord and Savior ( Colossians 2:17). For indeed Christ is our Passover Lamb and has been sacrificed for us. Christ says we must eat of His flesh and drink of His blood (John 6:53-58,63-64). As branches within the body of Christ let's keep this observance each year (Matthew 26:26-28). As we do so, we do this in remembrance of Christ our Lord ( Luke 22:19). It is our prayer that God will grant you understanding of the Passover observance.
