That all missionary efforts should be carried on through and administered under the authority of the local church. The Great Commission was given to the New Testament church; therefore, the authority to preach, baptize and teach rests solely with the local church. It is therefore the responsibility of the Church to train those who go and preach the Gospel of the Lord Jesus Christ, and to supervise their labors under the direction of the Holy Spirit.
The Churches auxiliaries are to cooperate with each other in carrying out the Great Commission. This cooperation shall be carried out in a manner as to preserve the unity of Faith and Canon of The Word of God in ministry application and practice.
MATTHEW 28:19-20
19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.
MARK 16:15
And he said unto them, Go ye into all the world, and preach the gospel to every creature.
ACTS 1:8
But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
2 CORINTHIANS 9:1-15
9 For as touching the ministering to the saints, it is superfluous for me to write to you:
2 For I know the forwardness of your mind, for which I boast of you to them of Macedonia, that Achaia was ready a year ago; and your zeal hath provoked very many.
3 Yet have I sent the brethren, lest our boasting of you should be in vain in this behalf; that, as I said, ye may be ready:
4 Lest haply if they of Macedonia come with me, and find you unprepared, we (that we say not, ye) should be ashamed in this same confident boasting.
5 Therefore I thought it necessary to exhort the brethren, that they would go before unto you, and make up beforehand your bounty, whereof ye had notice before, that the same might be ready, as a matter of bounty, and not as of covetousness.
6 But this I say, He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully.
7 Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.
8 And God is able to make all grace abound toward you; that ye, always having all sufficiency in all things, may abound to every good work:
9 (As it is written, He hath dispersed abroad; he hath given to the poor: his righteousness remaineth for ever.
10 Now he that ministereth seed to the sower both minister bread for your food, and multiply your seed sown, and increase the fruits of your righteousness;)
11 Being enriched in every thing to all bountifulness, which causeth through us thanksgiving to God.
12 For the administration of this service not only supplieth the want of the saints, but is abundant also by many thanksgivings unto God;
13 Whiles by the experiment of this ministration they glorify God for your professed subjection unto the gospel of Christ, and for your liberal distribution unto them, and unto all men;
14 And by their prayer for you, which long after you for the exceeding grace of God in you.
15 Thanks be unto God for his unspeakable gift.
2 CORINTHIANS 8:1-6
8 Moreover, brethren, we do you to wit of the grace of God bestowed on the churches of Macedonia;
2 How that in a great trial of affliction the abundance of their joy and their deep poverty abounded unto the riches of their liberality.
3 For to their power, I bear record, yea, and beyond their power they were willing of themselves;
4 Praying us with much intreaty that we would receive the gift, and take upon us the fellowship of the ministering to the saints.
5 And this they did, not as we hoped, but first gave their own selves to the Lord, and unto us by the will of God.
6 Insomuch that we desired Titus, that as he had begun, so he would also finish in you the same grace also.
1 CORINTHIANS 16:1-3
16 Now concerning the collection for the saints, as I have given order to the churches of Galatia, even so do ye.
2 Upon the first day of the week let every one of you lay by him in store, as God hath prospered him, that there be no gatherings when I come.
3 And when I come, whomsoever ye shall approve by your letters, them will I send to bring your liberality unto Jerusalem.
