If you believe the New Testament is inspired scripture then you know that physical circumcision is not a requirement for the people of God:
Col 3:11 Where there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond [nor] free: but Christ [is] all, and in all.
Col 2:11 In whom also ye are circumcised with the circumcision made without hands, in putting off the body of the sins of the flesh by the circumcision of Christ:
Gal 6:15 For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature.
Gal 5:6 For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love.
This was a huge, biblically documented issue in the early church. Acts 15 details the controvery. The biblical, Christian church decided that physical circumcision was not a requirement for salvation through Christ.
It is very true and still is that an uncircumcised person can't participate in the Jewish Passover, but when Paul commanded Christians to keep the feast of Passover and Unleavened bread there was no way that he was excluding uncircumcised gentiles.
What God did was to replace the jewish passover with the universal Lord's Supper.
God showed in the bible what Passover really signified...the death of Christ. Christ insituted the symbols of passover, the bread and wine, and commanded his followers to partake of them in remembrance of him.
That is how Paul refers to it among the Church at Corinth. He never calls it passover. No one ever calls the Lord's Supper "passover". "
I'm saying Christ instituted the symbols of bread and wine ON passover and commanded his followers to remember him, to follow in his steps.
There is no Christian passover. That's a myth. Christ is our passover. The feast we keep is the Lord's Supper in remembrance of Him.
As I see it you can go one of two ways. You can acknowledge that the Roman church has authority over you and celebrate it in the way that they proscribed hundreds of years after the death of Christ...or you can follow the example of Christ in the bible and celebrate Passover the same way he did and commanded us to.
Under the new covenant, that is true. But passover was an ordinance of the old covenant. It was a blood ordinance. One participated by the shedding of blood.
Under the new covenant the bloody passover has been replaced by the sacrament of the Lord's Supper, where we remember His death not with the shedding of blood, but with the sacramentals of bread (body) and wine (blood) of Christ.
It is very true and still is that an uncircumcised person can't participate in the Jewish Passover, but when Paul commanded Christians to keep the feast of Passover and Unleavened bread there was no way that he was excluding uncircumcised gentiles.
The fact remains that there is no biblical evidence of a new testament "passover" where the physically uncircumcised were permitted to participate. Paul and the others referred to the Christian ordinance as the Lord's Supper, not passover. That you cannot disprove.
