I hate to inform you that things have changed, the old world order has passed. We celebrate and remember what Christ has created through us and in us.
We are a new creation now and we celebrate the first day of the new creation. We undergo a spiritual circumcision in Christ now, not the old physical circumcision. We become members not of Israel but of the heavenly realms in Christ Jesus.
Our sacrifice now is not a bull but of praise. We don't resist stealing we exert generosity towards others, e.t.c.
What you believe is primitive and old school legalism. All things are new now in Christ Jesus, the methodology of legalism is stone dead.
I again ask---where does the bible say we are to celebrate a new creation on the 1st day of the week?
1Co 7:19 Circumcision is nothing, and uncircumcision is nothing, but the keeping of the commandments of God.
1Jn_2:3 And hereby we do know that we know him, if we keep his commandments.
1Jn_2:4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.
1Jn_3:22 And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight.
1Jn_3:24 And he that keepeth his commandments dwelleth in him, and he in him. And hereby we know that he abideth in us, by the Spirit which he hath given us.
1Jn_5:2 By this we know that we love the children of God, when we love God, and keep his commandments.
1Jn_5:3 For this is the love of God, that we keep his commandments: and his commandments are not grievous.
2Jn_1:6 And this is love, that we walk after his commandments. This is the commandment, That, as ye have heard from the beginning, ye should walk in it.
Rev_12:17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
Rev_14:12 Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
Rev_22:14 Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
Mat_5:19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
WE DO NOT KEEP THE CLOMMANDMENTS IN ORDER TO BE SAVED---WE KEEP THEM BECAUSE WE ARE SAVED.
Mat_22:40 On these two commandments HANG ALL THE LAW AND THE PROPHETS.
Rom 3:29 Is he the God of the Jews only? is he not also of the Gentiles? Yes, of the Gentiles also:
Rom 3:30 Seeing it is one God, which shall justify the circumcision by faith, and uncircumcision through faith.
Rom 3:31
Do we then make void the law through faith? God forbid: yea, we establish the law.
What God has spoken and written with His own hand no man can change no matter what anyone says.
Call it by whatever name you want---obedience to the word of God out of love for Him is what it boils down to.
Rom_6:16 Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?
2Co_10:5 Casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought
to the obedience of Christ;
