Define the only church in the New Testament.

To my new friend and opponent in this debate, I pray that what I say is never taken in a way other than how I'm presenting it, that being the love I have for your soul, as God has shown his love to me. My opponent states many false interpretations in which I will list as what I will be proving them to be, such as, 1. Christ never stated that only those who belong to a specific body of believers can be saved. 2."44 And all that believed were together, and had all things common; 45 And sold their possessions and goods, and parted them to all men, as every man had need." 3.Believers may have had been baptized and continued to gather together in a like manner during early Christian times, 4.any element of original Christian gatherings has been polluted by the religious aspect of what it has become. 5.The Ethiopian wasn"t given any instruction in how he ought worship, he was saved through humility (that he didn"t understand Esaias). 6.Says NOT to follow after anyone who claims to represent Christ. LUKE17:21. 7.That they don"t necessarily gather together to partake in worship or fellowship or traditions. 8.They could be enjoined to a body of believers, or they could be independent believers. My opponent argues that while Jesus was here on earth he forgave sins , and I agree with my opponent on this issue, as he also healed the sick and raised the dead, so we have no argument on this particular issues she presented, Luke 7:47-51, Luke Chapter 17, and Luke:12. My argument in respect to my opponents belief "is not" what Jesus could do in person while he was here on earth, as I humbly agree with my opponent on this matter completely, but, what his instructions were when he was preaching and when just before he ascended up into heaven his instructions to his Apostles were for us now to follow. I humbly ask my opponent to note the words I have put in parenthesis, which show that baptism was not an act to be delayed, it was an act that was to be done as quickly as possible. Also in parenthesis is the argument against my opponent that states, one "could be enjoined to a body of believers, or they could be independent believers", as I will prove that only one body, that being the body of Christ, is the " only "body, that one must be in, no exceptions. 1.Matthew 28:19 - Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: 1a. I ask my opponent to consider why Jesus would spend his very last seconds before ascending up into the clouds to put such emphasis on teaching and baptizing, if it wasn't essential to one's salvation? 2.Mark 16:16 - He that [believable and is baptized shall be saved]; but he that believable not shall be damned. 3. Acts 22:16 - And now [why tarriest thou? arise, and be baptized], and wash away thy sins, calling on the name of the Lord. 4.Acts 16:31-33King James Version (KJV), 31 And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house. 32 And they spake unto him the word of the Lord, and to all that were in his house. 33 And he took them the [same hour of the night], and washed their stripes; and was baptized, he and all his, straightway. 5.Acts 2:41 - Then they that gladly [received his word were baptized: and the same day there were added [unto them] about three thousand souls.] 6.Ephesians 4:5 - One Lord, one faith, one baptism, 7.Ephesians 4:16 - From whom the whole body fitly joined together and compacted by that which every joint supplieth, according to the effectual working in the measure of every part, maketh increase of the body unto the edifying of itself in love. 8.1Corinthians 12:27 - Now ye are the body of Christ, and members in particular. 9. Colossians 1:18 - And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all [things] he might have the preeminence. Worshipping together every Lord's day is a command. 1. Hebrews 10:25 - Not forsaking the assembling of ourselves together, as the manner of some [is]; but exhorting [one another]: and so much the more, as ye see the day approaching. 2. John 4:23 - But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him. 3. John 4:24 - God is a Spirit: and they that worship him must worship him in spirit and in truth. 4.1 Peter 3:8 - Finally, [be ye] all of one mind, having compassion one of another, love as brethren, [be] pitiful, [be] courteous: 5. John 17:21-23 - That they all may be one; as thou, Father, [art] in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me. (Read More...) 6. Acts 2:44-47 - And all that believed were together, and had all things common; 7. Acts Chapter 2 - 44 And all that believed were together, and had all things common; 45 And sold their possessions and goods, and parted them to all [men], as every man had need. 46 And they, continuing daily with one accord in the temple, and breaking bread from house to house, did eat their meat with gladness and singleness of heart, 47 Praising God, and having favour with all the people. And the Lord added to the church daily such as should be saved. CONCLUSION I firmly believe that my opponent must agree that I have left no room for doubt, that the church [s] of Christ is the one and only church defined in the New Testament. . In conclusion, I leave my opponent to ponder this verse which shows that one can only be in the saved, the church, which is the body of Christ, by adhering to this verse below, which I give as undeniable proof . 1.1 Corinthians 1:10 - Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing, and [that] there be no divisions among you; but [that] ye be perfectly joined together in the same mind and in the same judgment.
