Eph 1:18  The eyes of your understanding being enlightened; that ye may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints, 
Eph 1:19  And what is the exceeding greatness of his power to us-ward who believe, according to the working of his mighty power, 
Eph 1:20  Which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places, 
Eph 1:21  Far above all principality, and power, and might, and dominion, and every name that is named, not only in this world, but also in that which is to come: 
Eph 1:22  And hath put all things under his feet, and gave him to be the head over all things to the church, 
Eph 1:23  Which is his body, the fulness of him that filleth all in all. 

Eph 2:11  Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands; 
Eph 2:12  That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world: 
Eph 2:13  But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ. 
Eph 2:14  For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us; 
Eph 2:15  Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace; 
Eph 2:16  And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby: 
Eph 2:17  And came and preached peace to you which were afar off, and to them that were nigh. 
Eph 2:18  For through him we both have access by one Spirit unto the Father. 
Eph 2:19  Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God; 

Gen 17:9  And God said unto Abraham, Thou shalt keep my covenant therefore, thou, and thy seed after thee in their generations. 
Gen 17:10  This is my covenant, which ye shall keep, between me and you and thy seed after thee; Every man child among you shall be circumcised. 
Gen 17:11  And ye shall circumcise the flesh of your foreskin; and it shall be a token of the covenant betwixt me and you. 
Gen 17:12  And he that is eight days old shall be circumcised among you, every man child in your generations, he that is born in the house, or bought with money of any stranger, which is not of thy seed. 
Gen 17:13  He that is born in thy house, and he that is bought with thy money, must needs be circumcised: and my covenant shall be in your flesh for an everlasting covenant. 
Gen 17:14  And the uncircumcised man child whose flesh of his foreskin is not circumcised, that soul shall be cut off from his people; he hath broken my covenant. 

Paul schools the Apostles in regards to Church doctrine:
Gal 2:1  Then fourteen years after I went up again to Jerusalem with Barnabas, and took Titus with me also. 
Gal 2:2  And I went up by revelation, and communicated unto them that gospel which I preach among the Gentiles, but privately to them which were of reputation, lest by any means I should run, or had run, in vain. 
Gal 2:3  But neither Titus, who was with me, being a Greek, was compelled to be circumcised: 
Gal 2:4  And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage: 
Gal 2:5  To whom we gave place by subjection, no, not for an hour; that the truth of the gospel might continue with you. 

Day of Pentecost/Nation of Israel only, Apostles were required by the Law to attend.
Act 2:14  But Peter, standing up with the eleven, lifted up his voice, and said unto them, Ye men of Judaea, and all ye that dwell at Jerusalem, be this known unto you, and hearken to my words: 

Apostle’s following the Law (Temple prayers 3 times a day) after the Crucifixion of Jesus.
Act 3:1  Now Peter and John went up together into the temple at the hour of prayer, being the ninth hour. 

God gives Peter a vision regarding the Church.
Act 10:9  On the morrow, as they went on their journey, and drew nigh unto the city, Peter went up upon the housetop to pray about the sixth hour: 
Act 10:10  And he became very hungry, and would have eaten: but while they made ready, he fell into a trance, 
Act 10:11  And saw heaven opened, and a certain vessel descending unto him, as it had been a great sheet knit at the four corners, and let down to the earth: 
Act 10:12  Wherein were all manner of fourfooted beasts of the earth, and wild beasts, and creeping things, and fowls of the air. 
Act 10:13  And there came a voice to him, Rise, Peter; kill, and eat. 
Act 10:14  But Peter said, Not so, Lord; for I have never eaten any thing that is common or unclean. 
Act 10:15  And the voice spake unto him again the second time, What God hath cleansed, that call not thou common. 
Act 10:16  This was done thrice: and the vessel was received up again into heaven. 

AD59, 29 years after Pentecost some Jewish believers were still following the law.
Act 21:17  And when we were come to Jerusalem, the brethren received us gladly. 
Act 21:18  And the day following Paul went in with us unto James; and all the elders were present. 
Act 21:19  And when he had saluted them, he declared particularly what things God had wrought among the Gentiles by his ministry. 
Act 21:20  And when they heard it, they glorified the Lord, and said unto him, Thou seest, brother, how many thousands of Jews there are which believe; and they are all zealous of the law: 

Paul followed the Law in order to be an affective witness to the Jews.
Act 21:21  And they are informed of thee, that thou teachest all the Jews which are among the Gentiles to forsake Moses, saying that they ought not to circumcise their children, neither to walk after the customs. 
Act 21:22  What is it therefore? the multitude must needs come together: for they will hear that thou art come. 
Act 21:23  Do therefore this that we say to thee: We have four men which have a vow on them; 
Act 21:24  Them take, and purify thyself with them, and be at charges with them, that they may shave their heads: and all may know that those things, whereof they were informed concerning thee, are nothing; but that thou thyself also walkest orderly, and keepest the law. 
Act 21:25  As touching the Gentiles which believe, we have written and concluded that they observe no such thing, save only that they keep themselves from things offered to idols, and from blood, and from strangled, and from fornication. 
Act 21:26  Then Paul took the men, and the next day purifying himself with them entered into the temple, to signify the accomplishment of the days of purification, until that an offering should be offered for every one of them. 
(Law of Christ)
1Co 9:19  For though I be free from all men, yet have I made myself servant unto all, that I might gain the more. 
1Co 9:20  And unto the Jews I became as a Jew, that I might gain the Jews; to them that are under the law, as under the law, that I might gain them that are under the law; 
1Co 9:21  To them that are without law, as without law, (being not without law to God, but under the law to Christ,) that I might gain them that are without law. 
1Co 9:22  To the weak became I as weak, that I might gain the weak: I am made all things to all men, that I might by all means save some. 
1Co 9:23  And this I do for the gospel’s sake, that I might be partaker thereof with you.
