There were many times when obedience to Mosaic law could have been added to Christianity. It never was. Only people who desire to still be under the law try to make the scriptures say that Christians are still under it. Real Christians know that their works at the law are dirty rags before the Lord. Only the Lord Jesus Christ can make us clean and keep us clean.
Acts 15:5-11
[SUP]5 [/SUP]But there rose up certain of the sect of the Pharisees which believed, saying, That it was needful to circumcise them, and to command them to keep the law of Moses.
[SUP]6 [/SUP]And the apostles and elders came together for to consider of this matter.
[SUP]7 [/SUP]And when there had been much disputing, Peter rose up, and said unto them, Men and brethren, ye know how that a good while ago God made choice among us, that the Gentiles by my mouth should hear the word of the gospel, and believe.
[SUP]8 [/SUP]And God, which knoweth the hearts, bare them witness, giving them the Holy Ghost, even as he did unto us;
[SUP]9 [/SUP]And put no difference between us and them, purifying their hearts by faith.
[SUP]10 [/SUP]Now therefore why tempt ye God, to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear?
[SUP]11 [/SUP]But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they.
Circumcision wasn't the yoke that the fathers and disciples could not bear. Working at the Mosaic Law, the 10 commandments, is the yoke that the fathers and disciples could not be perfect at, no matter how hard they tried.
The eternal law of God written on stone...
2 Corinthians 3:7-8
[SUP]7 [/SUP]But if the ministration of death, written and engraven in stones, was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away:
[SUP]8 [/SUP]How shall not the ministration of the spirit be rather glorious?
